I am upgrading to a GeForce GTX 470 (Fermi) SuperClocked 1280MB 320-bit GDDR5, I was wondering how much of an improvement it will be over my 9600 GSO 364mb. Will it be like running two 9600 GSO's in SLI? or better? I already bought the thing so I am just wondering if it's going to be better than my Dual 9600 GSO's or not... and if it's a step towards better, I may just go ahead and buy a second 470. Any words you guys want to share?
