Wow guys! I just sold my old card and I'm looking around for a good mid-range card. The things is though, reviews don't help all that much you see. I've been reading TONS of reviews the last week and one thing I noticed is that it's so dependent on the game how a video card performs. Example, card A beat card B in game z but in game x card B beats card A!
It's very hard to know which card is going to be the best for CoD until the game is actually released and tested. Even though I'm sitting on a crappy IGP at the moment I'm actually inclined for the game to be released FIRST before I make my judgement. Hopefully some cards will also fall a bit in price by then. Good luck on your findings and plz share your performance info after you've tested the game.
