That sounds right Cript. And its the out that is not beside the TV out.
I had a feeling that it was that one. The reason is because i just had a 7800GTX 256 which actually had a mark on each DVI output, with the one closest to the motherboard being "1" and the one beside the TV out being "2". And since both cards are from BFG, then i could only imagine that the 6600gt would be the same as the 7800gtx.
Of course, in case you guys are wondering, i exchanged the 7800GTX for a 6600GT because the 7800GTX was causing screen blips when my computer would boot up.
Anyhow, thanks a lot.
