I am looking to replace my NVIDIA GeForce 8500 GT with a new video card for basic / medium gaming.

I have a 300W PSU and a Core 2 Quad Q6600 processor. My specs are here:

I need some help with deciding which video card I should go with.

I have read some good reviews on Tom's site about the HD Radeon 6670

But I am also considering the Radeon HD 7750

Is my processor fast enough to support the 7750? I can probably overclock to 3Ghz. I likely won't add any new fans/cooling.

I am willing to install a new PSU if needed.

I'm pretty clueless when it comes to video cards so I'd really appreciate people's input
