Help with buying a new GPU

[zrith1]

Hello, I'm thinking of buying a 6850 graphics card in the future in order to run games more smoothly and wanted to know something. My current pc specs are:
Processor:Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz
Memory: (RAM) 5.00 GB
Graphics: ATI Radeon HD 5570
PSU: 350w

I pretty much only play World of Warcraft, League of Legends, Diablo 3, and other not very graphics intensive games. My question is, would upgrading to a 6850 let me be able to run those games on maxed out settings with a decent FPS (I don't want it to ever dip below 20fps) and would I need a new psu?(I'm pretty sure I would, but I want to make sure).

HD 6850 would let you play all of them maxed out except World of Warcraft, which would require using 2x MSAA instead of 8x MSAA. And yes, you'd most certainly need a new power supply unit.

a 500 watt with 24 amps is fine to run 6850 and rest of the system

I agree with both posters but on the PSU make sure you get a good brand. Not a good deal but a good brand like Corsair, Antec, Seasonic, XFX, Siliver Stone, and some models of OCZ. I will link you to a few of them and good luck to you.

I agree with DM186, you should get a new power supply to power the 6850 you are going to put in there.

All of the power supplies suggested should do perfectly, yet the CX500 should suffice if you are on a budget.
