This card is more or less identical to any other 7900 GTX on the market accept for two differences. The first is its memory is clocked slower and secondly look at the price. Performance wise these cards are only approx 3-5% slower than a 7900 GTX with full speed memory, but you can easily overclock these cards as well. So when you consider the price these are an amazing deal. Be quick! Stock will soon be gone!
Just another 150-200 bucks difference. The choice between 2 7900GS and on 7950gt is 30 bucks.
