I haven't been much of a gamer for the last couple of years, but I recently started exploring SL again and have been enjoying it. I decided to update my Nvidia GTS 250 card. It was really loud and getting dated. I found a great deal on a Radeon HD 7850. So far I'm pretty bummed out, I can't really tell a difference between the two cards. On Ultra I was getting around 12 fps with the Nividia, and with the Radeon I'm getting maybe 16 fps. On lowest settings I was gettin a a higher frame rate with the old card. Looks like I didn't do my homework, AMD cards aren't great for SL, but the 7850 should perform better then this? Any ideas?
