Liquid Cooling + Pushing Overclock -OR- Second GPU + SLI for Real-World FPS Gain?

post #1 of 33
Thread Starter 
I'm looking at building a new system and wondering whether the last few hundred dollars would be better spent on (1) a full liquid cooling setup and pushing for more overclock on the CPU and GPU; or (2) adding a second GPU for an SLI setup.

The basic hardware will be something along these lines:
  • i7 4770K 3.50GHz
  • 16 GB DDR3-1866 RAM
  • MSI Z97-GAMING 5 Motherboard
  • Nvidia GTX 780
  • 256 GB Samsung SSD

I will most likely be running a 24" Benq 144 Hz monitor, and I'd like to be able to solidly outrun the monitor's refresh rate on the highest possible video quality settings. If I could run everything at 1080p Ultra with 150+ FPS, that would be great, but I'll back off as needed on the quality settings to maintain performance.

The options I'm considering are (1) sticking with a good basic closed loop for CPU cooling and adding a second air-cooled GTX 780, or (2) putting in a full liquid cooling setup and trying to push the CPU and single GPU to the highest possible stable overclock.

A full liquid cooling setup would be a bit more expensive, but the cost seems to be in the range of $400 to $800 either way, depending on how good a deal I can get on the individual parts.

What I don't have a good feel for is how much a full liquid cooling setup will add to the headroom for overclocking the CPU and GPU, vs. just a standard closed loop on the CPU only.

I also wonder how much SLI vs. overclocking a single card is going to benefit most games. It seems like all games would benefit a bit from straight up higher CPU and GPU speeds. From what I've read about SLI it seems you need to be running double or triple monitors and games that can do something with them to get much mileage out of it. So I'm not sure how much most games are going to make good use of the wider pipeline, if I'm only running a single monitor anyway.

I'm curious why one would by a quad on the X79 platform... should have went Z87/Z97 and a 4770K as you overpaid for the board and ram due to quad channel requirements of the platform.

Anyway, a couple of things need cleared up.......

1. You really shouldn't lower the resolution on LCD monitors as the image will not be optimal. If you need to gain FPS, lower some in game settings, but leave the monitor set to its native resolution.

2. You will get much better FPS gains with SLI. Hands down, period. No debate there (assuming you are getting more than 10% scaling which of course always happens, really).

3. You will want to crank your CPU when going SLI with these monster cards at 1080p. That is going to allow the cards to stretch their legs with such a 'meager' resolution for such beastly cards.

You're probably right, and I will be doing a bit more research before I decide on a final parts list.

Noticed you just joined today, I ran into someone this morning at a Tiger Direct store looking at basically the SAME stuff, was that you?

Not me. But I hope whoever it was finds what they were looking for.

rolleyes.gif haha had to ask, was just too coincidental. Anyway, I have to agree with Earthdog on all points. However, it's not like you'll be hurting yourself by going with an X79...in fact it will give you some options if you get an upgrade itch later, he's just trying to save you a few bucks, so keep that in mind. And yeah, games look absolutely terrible in different resolutions on my screen, so that's spot on accurate too.

I guess this is the sort of thing that makes me wonder.

I read a recent Tom's Hardware review where they were comparing an SLI review setup from last year (dual GTX 770) to their latest one with a single GTX 780 Ti. The new system came out ahead in most of the actual game tests, except when they were running triple monitors. It wasn't strictly apples to apples since they changed up all the components in making the new build, but basically it seemed like the higher CPU clock and a higher performing single card were coming out on top except when you had gigantic resolutions like 5760x1080 and three panels involved.

It sounds like your comment is also saying a bit of the same thing. The power of dual cards is unquestionably more than one card; but the system might not be able to do much with all that power in a single monitor setup, unless the CPU is jacked way up (and maybe not even then?). That's why it seemed to me that without a gigantic graphics load in play that is going to fully exploit two GPUs, there may not be much benefit from the second card, and the only real gains are going to come from just pushing the CPU and single GPU harder.

It will, regardless of overclock on the CPU, be better than one card. In order to get the most out of those two cards at that resolution you will want to overclock the CPU. If your goal is 144 FPS+ at 1080p, you will likely need to lean(overclock) on that CPU for best results. But with one card, unless it is an old title, 144 FPS @ Ultra across all games is not possible without sacrificing settings to do so.

So it sounds like you're saying that with a single card, the GPU is going to be a bottleneck, to the point that at 1080p some things will only run high frame rates at reduced settings. And with two cards the CPU will be the bottleneck, but overall the system will top out at higher frame rates on max settings, even though the cards might not be fully taxed. If I'm understanding it right, then that makes sense. Thanks.

My solution, go SLI as the numbers will likely show that you'll get a higher real world FPS gain. THEN overclock both cards devil.gif



Also, even though you listed your specs in the first post, when you get a chance you should fill them out for your signature here: http://www.overclock.net/lists/component/manage/type/RIG
