My son's original computer died and he's using a hand-me-down for now, but he cannot play any of his current games because the onboard video card just doesn't cut it. I ran a search of the Dell site to see what cards can work for this, but the reviews said that they were all not good for gaming. Does anyone have a recommendation for something that will A) fit in the SFF, B) conform to the 305 W, and C) still be good for gaming? I don't want to waste money only to have it not work...
