SLI Titans

[josh_05]

I think it will be fine, i just got MSI afterburner OSD up in Crysis 3 on my system running the game 100% maxxed with 4x MSAA instead of 8x at 2560x1440 and both my gtx 670s were running at over 90% the entire time i was playing that i noticed... This is running on an old Core i5-750 @ 3.2ghz base clock with turbo disabled. The 3570k is a current gen CPU, mine is 4 years old and seems to do fine.

The main thing you wanna look at for your PSU is how many amps on the 12volt rail as a single titan needs 42amps..Per the evga website.

Honestly having and i5 on a rig like that is just so silly. It would be much more beneficial to wait for the stuff that can do 4k and all that natively instead of buying something now that will be outdated by the time you come to use it. Either upgrade to a socket 2011 i7 or just wait for a while and get something better when there is much better 4k support. Also what games and stuff like that are you going to need all that gpu horsepower for. If it is some games occasionally and mainly video editing you are better going with a quadro or a tesla card for NVidia instead. I suggest that you upgrade to a socket 2011 and get that 3930k because there is not much point in getting a 3960 or 3970x. Also if you get this build all done then make sure that you are running folding@home when you are not using those cards or the cpu because you should be able to get a very decent amount of points per day indeed.

That's for the whole system, and not just the card alone. The Titan is quite energy efficient, so an 850W PSU with 70A on the +12v rail(s) is more than sufficient. For a couple of weeks, I had my system (3960X + 3x HD7970) powered by the HX1050, and it was managing it......it did run hotter than usual, hence my change to the X-1250.

Thanks for all the awesome info everyone. :)

Just so everyone is clear, I already own the 3570k. I may upgrade it eventually (and the motherboard along with it), but I see no reason to do so now.

Also, I will likely upgrade my PSU as well, per everyone's suggestions. I'll look at a 1000-1250 watt PSU to give me a little overhead for overclocking as my system will be water cooled, so it'd be a shame to not OC anything with that setup. I'm sure my 750 watt will last until I do that.

When it comes to 4k, I'm just looking to be able to handle it. In the sense that I can still game at that resolution with at least 60 FPS. Lowering details is fine imo for that, so long as it's still decent, which, for me, is at least Medium-High on most games. The fun part is that gaming at 4k means I won't be using Anti-Aliasing at all. And that tends to be what stresses GPU's the most. Though Particle effects are up there, nothing is more stressful than x16 AA from what I've seen. Why would I need AA when my monitor has such a massive resolution (similar to pixel density)? It has built in AA. lol

Also, GamerDude, if you aren't mining Bitcoins with that rig when you aren't gaming, you're burning (potential) money. Just a thought.

Epic Voah. Good info. Will definitely help me later.
