LOL...i can't believe you are asking this. It will run Far Cry the best it can be run. Far Cry isn't that demanding on today's cards, being as the game as a year and a half old.
alright.. my cpu kind of worries me.. i haven't built the computer yet.. i have my mobo/cpu/ram sitting behind me right now..just waiting on the gc to come thursday..
will there be any games that i'll have problems with?
None at all. Even games based on the Unreal Engine 3 will run nicely. You can expect to run games maxed out for another 6 months or so, after that you can expect Med. settings on 1280x1024 resolution with 60-90fps.
