So now the question is, what makes the difference between loops? Ideally we would want a loop to function at a very low DeltaT. Meaning we would want the rads/fan to be able to extract heat efficiently without having to force the loop into higher temperatures. Since the higher the loop's temperature will be, the higher the temperature of our silicon. A loop is a loop, block is a block, there's not that much to it AFAIK. Some people use different mixtures in their water, not exactly sure of details on that and how it affects cooling performance. The big thing is radiator space and the fans on the radiators - one loop with a 240mm rad and 120mm rad on a CPU and GPU, with three "meh" fans, might be able to keep the delta T at like 20c - but if you added a 360mm to it and ran a better fan setup (replaced with good static pressure fans, turned up, or just more fans) you might be able to dissipate that much heat with the water temp 10c lower, so all of your components would be 10c lower. Of course you're dealing with an asymptote (water temp can get closer to ambient temp, but it gets exponentially more difficult to make it 1c closer for every 1c that it is) but the idea is to be at a good place on the curve, and that requires more rads or better heat dissipation through rads/fans, scaling with the amount of heat going into the loop | ||

You'd want to give it a shot but it's probably hella-expensive! | ||

I'm not really sure what those other letters like s or t mean near it.. :/ | ||

EDIT: Also i5 4670 right? I'm not really sure what those other letters like s or t mean near it.. Yea, s/t are bad (mentioned in OP but understandable if you didn't read the whole thing!) You could get a lower tier option like the i5-4430 - but honestly they're 3.2ghz vs like 3.8 when turbo boosted (and you should expect turbo on desktop), it's a pretty large difference, and they're usually not expensive enough to justify getting the cheaper one, unless you're going for quad-core intel on minimum budget | ||

Also R9 270X or maybe something lower tier, keeping in mind its mostly sc2. Thanks for fast answer! Yeah you don't need an aftermarket cooler if you're not going to overclock. Good motherboards to look at are H81 or B85 chipsets. MSI make them cheap I think, maybe ASRock too. Something around €45-50 is how much they cost in Germany. http://www.amazon.de/MSI-7817-019R-Mainboard-Sockel-Intel/dp/B00EPLE3J4/ref=sr_1_1?ie=UTF8&qid=1384444594&sr=8-1&keywords=MSI H81 The T and S suffixes are for power saving stuff (also known as "terrible" and "sucky". They aren't recommended. Buy a normal 4570/4670 without a suffix and you're good to go. You may want to read the OP, there's information in there you might have missed. | ||

But yeah, thanks anyway, gonna try to do some more research myself as well about lower end motherboards. | ||

You'd want to give it a shot but it's probably hella-expensive! It's also a good bit of work where you have to be very careful to not destroy your parts. The parts in the loop can react with each other through the fluid depending on the metals and plastic used. The fluid mix is also important. You really need to like tinkering with it for it to make sense. If it's not fun, I feel it's too much. A multi-GPU setup might still make sense to water-cool as without room a GPU will have problems staying cool when using an air-cooler. | ||

It's not like I'm going to make myself a custom loop, have you seen my rig? xD Edit: yeah thing is I don't think crossfire is ever really worth it. I'm probably only ever going to game on a single monitor, no need to go overboard with triple monitor gaming set ups. One high end GPU for one high end monitor should be sufficient and that can be cooled just fine with high end air cooling. | ||

Any particular manufacturer you recommend? For 270x i was looking into asus with their direct cu2, but for 270 there seem to be a lot of different stuff. Also if 270x is just higher clocked 270 then given efficient cooler i should just overclock 270 to match 270x right? | ||

One high end GPU for one high end monitor should be sufficient and that can be cooled just fine with high end air cooling. 780ti is good enough to get higher FPS on 1440p* than 680/7970 can get on 1080p. That's mind-blowing in of itself - i can't wait for stuff to push those cards at 1080p. *~3.69m pixels vs ~2.074m Also if 270x is just higher clocked 270 then given efficient cooler i should just overclock 270 to match 270x right? There might be power limits or something, theoretically yes but maybe not. They'll be close, anyhow. Cooler shouldn't be the biggest deal on a low end card. ^Guru3d reports 63c load on asus 270, so freezing for a GPU. Bit hotter VRM, but we're talking about a ~140w under gaming load card, it won't scream for cooling like 290/290x/780 will | ||

It seems like Asus is using downgraded cooler on the R9 270 compared to the R9 270X. But the Direct CU II cooler on the plain R9 270 still did really well: http://www.anandtech.com/show/7503/the-amd-radeon-r9-270x-270-review-feat-asus-his/16 MSI's been doing pretty well of late too, but I'd rather take the known commodity above. If AMD is binning these chips, then maybe the average R9 270X might overclock better than the average R9 270. And there may be differences in allowed clock speeds, voltages, power limits. I didn't check those things. But there mostly seems to be little reason to go for the R9 270X for the reasons you say. | ||

Probably not worth waiting for, but it's just a little cheaper than 270x. That's a pretty nice build though, for running stuff like sc2 well, streaming and running newer games great at non-max graphics settings (: | ||

Interesting idea, SLI solution but single board slotting in above the 770/280x. Maybe they wrote memory bus and VRAM wrong though, like 690/7990 they'd still be on 256-bit bus and the VRAM would be mirrored, not additive. 1250mhz clocks on the cores i'd guess are doable, though | ||
