Gigabyte 6800GS/SLI/watercooling
 

With regard to the SLI, I am disappointed a little, certainly the profit with programs as 3DMark (for the bencheurs) is very interesting, but on the level of the plays, it is not always convincing. -- Well on, the processor and the resolution of posting exploit the performances enormously. With the proper perspective, I think that I will have to carry out the tests in SLI with 1600x1200. I thus advise you more the purchase of a 7800GTX that of two 6800GS. The SLI remains very interesting with an aim of a upgrade, but once more, that depends on your starting budget!
