I don't get it. I have three comps, two with the BFG 7800GTX cards in them, and one with a EVGA 7800GT card. I'm currently using the step-up program on the 7800GT to go to the 7900GTX. While I was doing the step-up stuff this morning, it hit me that the 7900GTX card from EVGA is only $20.00 more than the BFG 7800GTX is selling for. Is the performance increase that minimal between the two..? I don't understand the pricing.
