Thinking of upgrading from my 8800 GTS 512mb to card stated above and was just wondering what sort of perfrormance you guys are getting, and whether I would be able to run decent aa/af at 1920 x1200. I'm getting between 45-60 with everything on high except shadows, with bloom and HSAO set to off. I'm quite happy with this performance apart from the jaggies! Would really love some AA! Looking at reviews it seems the HD 5850 struggles at 4xAA so would it be worth me going for a 5870 bearing in mind I need a new PSU aswell? Or keeping my card till ATI refresh? Other components are [email protected], 4gbDDR2 Ram. Windows 7 64bit.
