I'm looking to buy a graphics card for my PC that I built. i have looked at many Graphics cards and want one in the GTX 660 non ti series. i can't decide on which on to get. some are faster than others, but others are slower and more expensive. i have heard that EVGA GTX card are very good. I don't have good airflow in my case i have only got 1 140mm fan that will placed above the graphics cards and 1 80mm at the back.
