EPTcan someone simplify it in a easy explanation?
when i look up what mantle is, there is more terms that pop up leading me to have to dig more, which the more i dig, the more digging i end up having to do, (its a never ending cycle)

Basically when you play games today, your game engine sends information to your GPU so that the GPU displays what you see on your screen. To allow your GPU and the game engine to communicate, they need a link. That link is DirectX. So basically it goes like this: Game engine -> DirectX -> GPU -> Monitor The way mantle works is that it eliminates the DirectX step. This increases performance somewhat significantly since we lose a step (less shit to compute). So what it would be with Mantle is this: Game engine /w mantle -> GPU -> Monitor There is a drawback however; it's that the game engine itself has to be coded with mantle in mind, not DirectX like most games are. This means that developers, if they opt to go with Mantle, will be forced to code a game for both Mantle and DirectX (as many people own Nvidia cards). This is a huge investment of time and money for a gaming company. It already costs quite a bit to release games that work on both PCs and consoles and Mantle would basically add to that. Nonetheless, the benefits of bypassing DirectX and working with the GPU directly are definitely real. NB: this is my understanding of mantle so maybe I left out some key points to consider. Also noteworthy is that Nvidia won't have Mantle, meaning if Mantle works out and game developers start coding games to work with Mantle, we have a pretty big win for AMD. | ||

Good brands to look into are Gigabyte, ASUS and MSI, perhaps also Sapphire. Those brands have great heatsinks and you can overclock them. You might be able to find a cheaper motherboard if you're not going to overclock. No reason to get an H87 board when B85 or H81 chipsets are cheaper and will work fine for a gaming rig. Or you can dish out some more cash and get a 4670k and a Z87 motherboard, with OC capability. Thanks for the reply! The cheapest 280X is $350, $40 more than the 7970. Would the performance increase be worth the difference? It'd be the same brand and same warranty. Would something like this for the motherboard be sufficient? http://www.pccasegear.com/index.php?main_page=product_info&products_id=24853&cPath=1491 There's an even cheaper one but it only has 2 USB ports. | ||

http://www.anandtech.com/show/7400/the-radeon-r9-280x-review-feat-asus-xfx/12 ^What you would be comparing is the XFX 280X (in red) to AMD's vanilla 7970 (in black). If you feel the edge the 280X has compared to the 7970 is worth $40, you have your answer. XFX and Powercolor aren't the same brand but they're the same "tier", so to speak. They both use reference PCBs with their own, non-reference coolers on that. Bigger brands have custom PCBs and coolers to go with that that allow for extra performance (through better overclocking capabilities), at a price. The cheaper motherboard you mentioned shouldn't have only 2 USB ports, that sounds weird. I checked: http://www.asus.com/Motherboards/H81ME/#overview It seems to have 4 on back panel. There's only 2 USB 3.0 ports, however. Edit: I could be wrong though. That's weird as fuck. Edit 2: OK it says ASUS H81M-E Motherboard, LGA1150, Intel H81 Chipset, 2x 1600MHz DDR3, PCI-E x16, 2x SATA3, 2x USB 3.0, Gigabit LAN, DVI, D-Sub, Micro ATX form factor. Backed by a 3 year ASUS warranty. Which I believe means it does indeed have only 2 3.0 ports and another number for 2.0 ports. Just 2 USB ports for one motherboard doesn't make any sense at all. lol ^^ | ||

Not taking OC into account, the Powercolor 7970 you're looking at is at 955/1375 compared to the 280x's 1000/1500. There's your $40 difference. I would probably pay for the extra $40.

I'd be saving $40 with the change in motherboard anyway, so I may as well go for it. Will two USB 3.0 ports probably be sufficient? Google has told me it doesn't make a difference for keyboards/mice, and I don't see myself regularly using external hard drives. | ||

a 280x is a 7970 is a whatever unless you're bothering about the different coolers, voltage unlocked versions, OC potential etc | ||

My friend just recently put a 770 into his system. It has 8 gigs of ram. I;m not sure what CPU he has but its an amd at 3.6ghz. His psu is some 600w thing from a brand I've never heard of. The gpu requires both and 8 pin and 6 pin pcie connectors. His cpu only had 2 6 pins open, and he used a 6 pin to 8 pin adaptor on one to connect the gpu. He says he can run bf4 on med settings fine, but when he puts it up to ultra it starts lagging like hell. I believe he has some molexs free, could the 6 to 8 pin adaptor be insufficient and cause the card to underperform? and if so then a 2 molex to 8 pin adaptor should work just fine right? | ||

Shadowplay also seems really good for recording games (there's nothing to replace g-sync and shadowplay.. they are kinda unique in function - while Mantle's major benefit is higher gpu performance - which you could always throw money at if you really cared, that's my view at least) I got a 770, but it's just soo hard to reccomend @26% higher price, 7970 has 3gb vram too well I have no plans on streaming things (only watching). also no plans on using 2 monitors...but if I do Radeon should be fine with that? anyone have any recommendations on which manufacture to get? I have no experience with gigabyte but thats my current choice only b/c thats what was suggested for a good mother board. I always hear asus is good but runs hot and loud..solved by having more fans..but I also will work in a windoless room with I would say less than perfect airflow | ||

BF4 uses a ton of VRAM. More than the 2GB the 770 has when you crank up textures and AA. | ||

I'm not sure whether we are talking about R9 280x or GTX 770 anymore. Most manufacturers are fine, I guess it depends on what you are looking for. The big three (ASUS, MSI, and Gigabyte) all offer a three year warranty as opposed to two years offered by AMD's partners (Sapphire, HIS). On Nvidia's side, EVGA offers the same three year warranty as the big three but their post-sale support is generally considered to be the best in the GPU industry (option to purchase extended warranty, step-up program, advanced RMA, forum community, etc). The noise and temperature difference between all of them should be similar under a gaming load and won't matter much at all probably. For the ~$300 cards, the ASUS R9 280x probably has the best PCB and heatsink design. MSI has the shortest PCB of all the R9 280x's if that matters to you but the rest of it is still reference design afaik. All the cards near ~$300 are voltage locked except for HIS IceQ x2 apparently. Sapphire Toxic is clocked the highest but also is ~$40 more expensive. | ||

Cyro is saying it's impossible to judge how good it is without comparing a monitor with G-Sync and a monitor without side by side.

The 770 is similar and offers things that I will probably never use. (Unless I am mistaken in what you guys are saying). Short or long PCB doesn't mean anything to me..I'll have to google it and read up on it. There is a low chance of me OC anything for now...so having the chance to do it is only a bonus but def not a requirement. | ||

There's a lot of mixed reports of whether a card is voltage locked or unlocked lol but I think the general consensus is that the HIS, XFX, and ASUS Matrix is unlocked. | ||

Can cards that run mantle still run DirectX? Is it it more like 1 or the other thing? There's OpenGL and Direct3D at the moment. AMD and NVIDIA provide support for both in their drivers. Direct3D is only on Windows (and something related and stripped on the consoles?). OpenGL is available everywhere, Windows, Apple's OSX, Linux, a stripped version on smartphones, etc. The consoles also always had something special perhaps similar to Mantle. That's what was meant when people said the games on a console can get more out of the hardware than on a PC. So games programmers already work and support a lot of different stuff to be able to have their game engine run on all the different systems they might want to sell their games on. Regarding Mantle and NVIDIA, on OpenGL, the GPU manufacturer's are allowed to provide special extensions that are unique to their GPUs. NVIDIA already did something with that a few years ago to get a similar performance increase as what AMD's trying to do with Mantle. That extension did not do that much for performance compared to normal OpenGL and Direct3D. It also was not used at all by games because it was exclusive to NVIDIA. The same might happen to Mantle, it might not do that much to be worth the work, and it might not get used because it's exclusive to AMD. | ||

In theory the Gigabyte card can clock the highest. Gigabyte uses the 60A IR3553B Power phases on all it's GPU's (well I don't know about entry level cards). They are slightly more efficient than what the other boards use. So even though lets say a GPU like the 780 Ti with it's 265w board limit (106% limit), even though all the cards can pull 265w, the Gigabyte card has slightly higher useable power. In practice though it doesn't really help clockwise, just slightly lower power consumption. Then there is the Classified cards from EVGA. They are completely unlocked once you hit a switch on the PCB. | ||
