EVGA’s 7950 GX2 really impressed HotHardware.  It started out tying and sometimes even beating a pair of 7900 GTs, but when they got a 15% overclock on the core and ~25% on the memory all bets were off.
“As you would expect form a card with a pair of G71 GPUs and 1GB of frame buffer memory running in tandem, the EVGA e-GeForce 7950 GX2 performed much like a pair of GeForce 7900 GT cards running in SLI mode. The EVGA e-GeForce 7950 GX2 was clearly much faster than any of the other single-GPU based cards we tested, and it traded the top spot in most tests with the 7900 GT SLI setup.”
