you'll need a minimum of 500w psu for a 4870 and a 450w for a 5750. Id recommend getting a new PSU firstly and going at least 50-100w over the specs required for whatever GPU you go for. If you want it for gaming I'd recommend at least an ati 48** or 57** (the 56** are ok nothing too special) or a GTX 270 and up or GTX 460 and up. But it all depends on your budget.

That said a 8600 gt will probably do ya requires a 300w (although it's a 512mb card) but the GTS and the 8800 and need a 400w and up PSU

But I'd still recommend a PSU upgrade regardless and go to a 550w or 600w and get a 57** or a gtx 4**
