Thanks for the replies, sorry for my late reply lol.
I dont really have a budget, but at the same time i dont want to spend too much on this PC. I can find this card on ebay for like 40 bucks, but if there is something else that would work better then the GT240 with out costing too much more i would consider it. Not trying to upgrade the Power Supply either so keep that in mind.
Thank again for the replies.
EDIT: Also, would be PC be able to handle the GT240 1Gig version?
