Upgrade advice

[c1001]

Looking for a video card upgrade recommendation: I have a four year old rig with an A8N-SLI mobo, AMD64 4800+ CPU, 2GB RAM, and 2x 7800gtx PCI-E cards running on XP-MCE. I am not ready to upgrade the whole system for another year but would like to move up to a newer video card. I threw in a friend's single 9600GSO 1.5gb card and saw definite improvements in framerates and quality over my current SLI, but I want more!

Any advice on a newer video card that will bump up the performance without getting completely bottlenecked by the CPU?

What's your budget? Where do you live in the world? What power supply do you have?

Never mind. Bought a HD4770. For $110, I don't care if it is bottlenecked.
