^^^ on low eye candy.
your card will play it fine on 1080p, just no eye candy like AA. dont need it much anyways. get the demo and test.
Ya, even low-high on the game doesn't seem to make much of a difference. If it runs decent, I wouldn't spend $500 to upgrade to play 1 game, that I don't even really like. lol.
Download the demo, try it out, see if you're happy with your systems performance.
