I don't use the newer one's yet as they are not supported with Rivatuner and I use that program for a few things.
On the plus side though I never had any of the problems some people were having with bad lag or rubber banding on away missions so it is all good
GTS 210 was a waste. I would have bought a better card vs a lifetime sub. I run SLI 260's (192/216) and they don't even have to try to run this game. The only problem is Post Processing and heat. Doen't look that great anyways so I keep it off, everything else pretty much max running 1920*1080 and I don't move more than 2 frames off 60.
For those with heat issues, check post processing. That option alone can raise my temps around 15c on the main card and 10c on the lower. I tested it for hours with a ton of screenshots. To bad they are all black lol. Anyone know the command to not remove the UI from screen shots?
