I bought a GTX 480 a few months ago to replace my dual sli 8800GT's and I'm amazed at the performance. I only use a Quad core 8200 though so if I get a second GTX480 it will be majorly bottlenecked by the CPU without an i7. Next year they are bringing out new processors (INtel with it's Sandybridge processor at almost 5 Ghz and AMD with bulldozer). Not to mention that Kepler form Nvidia boasting 3-4 times faster speeds than the GTX 480 is coming out next year too. If i was looking to upgrade, i'd wait till next year to get these new processors and video cards. By then the old gen GTX480 cards will be much cheaper anyway. It all depends on how much bang you want for your buck. Pay a premium and get the new Kepler and Sandybridge/Bulldozer and have crazy "beat-all-your-friends" performance, or pay a bargain price for the old cards (which are now premium). Wait till next year people!
