SC2 in particular uses multiple cores very poorly, so all of your performance comes from the first two (I think) cores It's a somewhat common theme in software - for anything with a low but non-zero amount of parallelization you benefit from at least a second core because the main one can split or offload the X amount of non-serial stuff - the only time that there'd be no benefit was if the entire workload was singlethreaded. Very large parts of SC2's workload is ST but not all of it. That second core is still largely idle after taking on the work that it can so the benefits of extra cores beyond that are smaller, in SC2's case far smaller. I have noted enabling or disabling sound entirely causing FPS changes in SC2 and WoW but they haven't been that huge, haven't been present in other game benchmarks and i'd never play without sound so i haven't given it much more thought. I've done several 32 vs 64 bit benchmarks and sometimes the difference was in the double digit % but that's changed a lot over time as well. | ||

![[image loading]](https://i.imgur.com/bXeeKPe.png) minimum GPU load 4% during the moment of worst FPS, GPU boost isn't being used so it's at ~80% of full core clock. SC2 has been severely CPU limited since day 1 and then graphics performance has advanced far faster than CPU ST performance | ||

My room is 30°C right now with 20-90 fps and ~43°C gpu temp. gpu temp was never over 40°C on 64bit. 54 C is quite low. Throttling happens way up around 84 C and it's not uncommon for some cards to be in the 70's at 100% load. The card in my case sits around mid 60s when mining @ 65% fan. As a random bit of trivia, the Titan X (I think both the original and Pascal) throttles under 100% load. The cooler is just that bad. | ||

For instance, I was about to pull the trigger on an i7-8086K (40th anniversary), 32GB 2666mhz, 512 SSD + 1 TB 7200rpm, and an 1080 Ti 11GB, and 750W liquid cooled PSU ... 2300$ If you try to buy these similar parts yourself and build it, I was finding pricing between 2100-2300$. In this scenario, if you ask me, it makes perfect sense to just buy the pre-built. | ||

The main problem was a big spike around Jan-March when Bitcoin and Ethereum prices were at like 250% of normal. The 1080 TIs (which were a big favorite at the time) have multiple brands in stock at the original 750-850 price range. My 1080ti model is still $150 more expensive than it was at launch when i bought it, at this time in GPU lifecycle stuff would usually be well below MSRP on competing sales. r9 290/290x's were selling for 60% of MSRP in the same timeframe from the same stores but instead these cards are at 110%, 120% of what they could be had for a year and a bit ago, effectively twice as much as that. They haven't returned all the way back to launch prices and the end of generation sales are a whole quarter overdue so i'd say that we're still in the recovery process and probably will be for a while to come | ||

They might be taking a little longer than normal, but I don't think it's exceptionally so. Maybe you just got a good deal when they came out. | ||

Where are you looking? UK shops. We didn't usually get hit as badly with the mining stuff as US (because hardware is more expensive and power is a lot more expensive across europe) but the prices became highly elevated this time around and are still elevated over the launch prices today | ||

I plan to stream 1080 @ 60fps. It's just SC remastered which as we all know doesn't require anything great. I don't even keep on all the fancy graphics either. But from a streaming perspective, I should be more than OK with a 1080 Ti + i7 8700 + 16 GB RAM ... Can I get something a little lesser than 1080 Ti even and be ok for my needs? I don't particularly do anything else - though I have a dual monitor set up which I use for work (leveraging a KVM switch to go back and forth from my desktop to work laptop). Thinking to go to 3 monitors with this new rig. Though it looks like a 1080 Ti doens't have HDMI + DVI port, it has HDMI and display mini ports. My KVM switch is all DVI (since its a dual kvm switch), I've even had to use an HDMI to DVI converter to get that whole thing set up. Rather get a card that has an HDMI and DVI port in it so it's just plug and play with my current cables.... Does AMD have a line that is good or slightly lesser than the 1080 Ti which will serve my purposes but has HDMI and DVI? Other than that, basic web browsing, etc. I don't play any other games and probably will never plan to. I'm a Brood War only kind of guy  Even what I've stated is probably overkill for my purposes, but rather just get something that's going to be great for the next 7+ years and not look back.Thanks. | ||

With the changes to WoW engine (Dx12) does the overall opinion that ST performance in CPU and better Nvidia performance still true? Few people have performed benchmarks and i can't myself because i don't own any kind of modern AMD GPU. dx11 is still faster than dx12 on Nvidia. dx12 outperforms dx11 on AMD, but AMD's dx11 was considerably behind Nvidia's dx11. The AMD dx12 vs Nvidia dx11 needs further benchmarking which requires win10 and a decent GPU from both vendors. --- The game is still highly reliant on CPU ST performance, now more than ever. 8.0 has removed some features that improved performance (such as blob shadows and exclusive fullscreen mode) while the new zones have more objects and detail than ever before; There's also a lot of water all over (with Boralus being surrounded by it) which is especially taxing on the engine. Performance has dropped, not risen; at least on every config i've been able to test. Overall when making the jump from 7.3.5 to 8.0 i saw a performance loss of 1.15x on one of my older cataclysm benchmarks (1.4x if setting object view distance back to about the same as legion) for reasons that i can't adequately explain. There was also an increase of input lag of 1 frame because of the removal of fullscreen mode. With dx12 there may be non-negligable core scaling beyond 4c4t but i wouldn't expect it to extend beyond 6c6t / 4c8t. The game may benefit from additional L3 cache (Intel's recent mainstream CPU's have 2MB of L3 cache per core, but any core can access all of the L3 cache at full performance) so a 6 core CPU has 50% more available L3 cache than a quad core and that may show performance gains on the 6 core CPU over a 4 core CPU which are not actually due to core scaling (as proven by disabling cores on the 6C and maintaining the elevated performance). Need more investigation on if that's a significant performance change or relatively negligible. | ||

I don't see any reason to get a 1080ti instead of e.g. a 1050ti The non-reference graphics card models can decide on their own IO, i'd imagine that plenty can take dvi-d and hdmi (although dvi-analog support has been largely dropped with this gen) | ||

I see it comes with HDMI and DVI that I need. Obviously 4gb is more than good enough for what I need to do. Think it'll stream 1080 @ 60fps smoothly? This could be an option too then I guess: GeForce Zotac GTX 1080 Mini. Ever heard of that one? It has both ports. 1070 also seems to have both ports too. | ||
