2x GTX 680's vs 780TI - Page 2

post #11 of 24
Two 680s will outperform a single 780ti in actual GPU power, the VRAM is what is getting you into trouble in Skyrim. Modded Skyrim eats VRAM like no other game, and upping the resolution to 1440p will also eat even more. For 1440p gaming, Skyrim especially, it would probably be worth it up upgrade to a gk110 or Hawaii card. Used R9 cards are plentiful and cheap right now thanks to miners dumping their gear.

You can stack gpu unit counts using SLI, but memory doesn't scale 100%. If one of the cards stall on an instruction, you will runt both frames since Nvidia SLI default is calculating each half every frame on both gpus, afaik.
I would recommend you search for a dynamic frame lock program like RadeonPro is to Radeons. Driver based frame locks prevent frames that are sent faster than the monitor can refresh the screen while in the mean time idling the gpu during scene refreshes and increasing the available power quota for a higher overclock. I don't know what 5 degrees celcius offers for Nvidia Gpuboost, but I suppose around 13mhz.

I would definitely go with GTX 780 Ti because with SLI you can get mini-stutters, which some people really hate. You have to maintain 60fps on a 60Hz monitor at all times with vsync enabled to prevent all mini-stutters from occurring. A single card would a lower input lag and 2Gb of VRAM is not going to be enough pretty soon, not @ 1440p and MSAA... BF4 already goes above 2Gb of V-RAM, although 2Gb cards don't seem to be stuttering either.

It's one of those things that if you already have a 680 then grab another, but if your upgrading from the 5xx or lower series then grab a 780/780ti

I had GTX 680 that I just sold to buy a GTX 780 Ti for the reasons I mentioned. I hate mini stutters and so do many others. I also want 3Gb of VRAM because it is future-proof. I also like Boost 2.0 and the original one that throttles OC at 69C. Then there are general SLI incompatibilities, etc. Its only my opinion!

I will keep the 680s and upgrade when the 880s come out. I guess I can blow my money on something different smile.gif

I would do since I could maintain steady 60fps but I have a 120hz monitor so any sub-120fps would result in constant micro-stutters. A single card would not, but I would need 3x SLI if not more to get steady 120fps for perfect smoothness.

2GB vram on 1440p will be a problem, I say get 780Ti or wait for 880.
post #20 of 24
I'm on 1440p and have no issues with my two 2GB cards running out of memory, playing games like BF4, Thief, Crysis 3, Tomb Raider and that's with using antialsing. I can't comment on future games but as of now I'm good
