Is your PC monitor resolution something like 1680x1050?
Your graphics requirement will be less for the 1680x1050 resolution but if your native resolution is 1080p then it wouldn't look right scaled down so I would suggest a more powerful card but in any case if you get a GTX 480 or faster you wont have any issues.
well if you can push your budget a little bit high and get the GTX 560Ti, it does great job @ 1680x @ high quality.
60 FPS, the game will run very smooth.
Also if you'll stick with a GTX 550Ti or GTX 460, is game is more than playable
Alright guys, thanks for all the info. I think I am going to push my budget a little bit up and get the 560ti that way I won't have to replace it as early as getting a weaker card. Appreciate the help.
