I am thinking of buying a new Desktop video card? Help?

right now, I have a GeForce 6600 GT Graphics adapter - 128 MB - GDDR3 but im thinking of upgrading it cuz it sucks when i play Starcraft 2.



So im deciding on a cheap 50 - 150 dollar gaming video card thats really really good for games



I have a few choices in mind:



EVGA 512-P3-N871-AR GeForce 9800 GTX+ 512MB 256-bit DDR3

XFX HD-485X-ZDFC Radeon HD 4850 1GB 256-bit GDDR3

Any suggestions?|||If your processor is a intel buy the EVGA 512-P3-N871-AR GeForce 9800 GTX+ 512MB 256-bit DDR3

but if your processor is AMD buy the XFX HD-485X-ZDFC Radeon HD 4850 1GB 256-bit GDDR3
