I have a 4850 that's just kind of sitting around and was going to throw it in my woman's computer. She has a Q9300 OC'd to 2.6 or 2.7 I think, 4GB DDR2 800, antec 750W PSU, 256MB 8800GT, 24" acer monitor. The game she plays the most is Oblivion, but also RTS games too. If it's only like a 5% difference, I'm not going to bother. I have a couple extra 4870 cards, but I think I'm going to sell those.
