Hello I'm for sure getting a new video card since mine is dying out on me now. My budget is around 170$ tight. This is my current setup Core 2 Duo e6850 stock, 2x1 gb ram corsair. I was thinking 5750 or 5770. I play TF2, L4D, I have intention of picking up Bioshock 2 and Left 4 Dead 2 so far. Thanks
