MWLL for crysis maxed out the 2GB immediately, ArmA used all of it quickly, even BF3 was getting near 2GB usage (which is weird because 5760x surround seemed to use the same memory as 3840x1024 surround). I'm planning on getting some 1920x1200 monitors in a few months when the Black Friday/cyber monday sales happen.
I think SLI 670 or 760s would be perfect for my current setup. If 2 275s is about a 560ti/570 range, and a 670 is one gen, or about like 15-30% faster than that. I'll be nearly triple the performance with two of those compared to what I'm at now.
On a 2GB card, I don't use AA. Or, if I do, it's only 2xAA. I'm not saying everything is smooth (Crysis 2 with DX11 and HD textures, Crysis 3 don't run great) but Battlefield 3 on high is OK. Saint's Row 3 can run on Ultra, although it does suffer some framerate drops there, so I tend to run it with Ultra settings, but with AA turned down to 4xAA or 2xAA rather than 8xAA.
To be honest, at 1200p, on my Surround rigs, I'm sitting far enough back that if I'm actually playing the game, rather than looking at eyecandy screenshots, I don't pay a lot of attention to jaggies. They only really become annoying during cutscenes, or times when I'm not actually doing anything.
BF3 is a bad one to use for comparison, because on a 2GB card it maxes VRAM out without choking... and on exactly the same settings on 4GB 670SLI, it tells me that it's using nearly 3.6GB. Now, if that was true, a 2GB card just wouldn't give playable framerates. I think BF3 checks the VRAM and caches as much as it can.
As much as I'd like to go GTX780... it feels a bit like a side-grade... I mean, sure, much more powerful GPU... but less VRAM than my 670s...
That and I'd still want two. And a new PSU. And possibly a new mobo and CPU. And... yeah, I'd have just spent a minimum of £1500 on that little venture.
