Hey, so I have finally decided to pull the trigger and get a 2560x1440p monitor (Dell U2713HM). Currently, I am running a 1.25GB GTX 570 and I know I will not be able to run anything, so it's time to upgrade. In my region, a GTX 660ti 3GB is about $50 cheaper than a GTX 670 2GB. I would like to get the GTX 670, but I'm concerned that the 2GB Vram may not be enough, especially when the new consoles come out.
From the benchmarks I have seen, it seems that when you put on some AA it can sometimes halve the FPS; is this due to a lack of Vram or will this always happen no matter how much Vram you have? At my resolution, would I see any benefit from the additional 1GB of Vram or should I spend the extra $100 and get 670's in SLI? Also,I have been reading a lot about the 192-bit memory interface on the GTX 660 ti being insufficient for 1440p resolution, is this true? and what exactly does it mean? Do you think either of these are a viable solution?
Thanks in advance,
