Actually I bought the 6800SLi set , one of the 7950GX2s, and one of the 8800GTXs. (although NVIDIA did give me another one later) I bought two Asus A8N 32 mobos, a Silverstone 750 watt quad rail, and a BFG 600 watt, not to mention a lot of other stuff.
Yeah, sure, I get some parts free from NVIDIA. I also spend a lot as well.
So I don't think your point is valid.
BTW- are people who get their cards as gifts from family members opinions invalid as well? Point being- you didn't/couldn't refute anything I said, all you could do is say "It's not true because you get free cards".
