Been reading some great things about the 8800 GT, a card that I can hope to afford, and provide enough of a jump over my 7600 GT to justify picking it up.
I like this quote from ExtremeTech:
This is, by far, the best bang-for-the-buck we've seen in years. It's a killer card, likely destined to be remembered with the same fondness as the GeForce 4 Ti 4200, Radeon 9700 Pro, or GeForce 6800 GT
Bang-for-the-buck is the name of my PC building game.
