I realize this has been talked about before but I am still confused. I am running at 1080p and will be upgrading from my sli'd gtx275 set up. I'm looking at sli'ing MSI N560GTX-Ti Hawk with 1gb memory or possibly the 560 ti 448 w 1280mb.
My question is with 1080p should i be thinking of 2gb cards? I want to be able to play bf3 at ultra settings.
The performance difference between 1GB and 2GB between most games is minimal if not non-existent (BF3 actually uses more than 1GB of VRAM; people on forums see crazy spikes of VRAM usage on that game; people with 1GB still get great performance).
However, if the price difference is under $100, I think it's worth it.
Games that utilize DX11, tessellation, and all those latest features are quite demanding on VRAM, especially with AA enabled at resolutions 1080p or more.
That extra VRAM can help in preventing memory leakage and such.
If you have the money for it, it won't hurt.
If you don't, you'll most likely be fine as well.
With the direction gaming is going, my worry is that new games coming out will require more and more ram, and rigs will quickly become obsolete. just because you have a ridiculous amount of ram today doesn't mean you will tomorrow.
For a long lasting rig that can hold up to the rigors of tomorrows software, would it be stupid to invest in something like trip 3gb cards? i thought they had the microstuttering worked out, and im not to worried about the price, but that doesnt mean i want to spend that much when i could get better results for less.
