ok, thanksIn order for SLi mode to work you'll need two cards of the same series, but not necessarily the same manufacturer.
An example is using an 8800GTX from ASUS and an 8800GTX from PNY. That combination will work.
If you tried an 8800GTX from ASUS and an 8800GTS from BFG it would not, since the two cards are not of the same type.
your right. im just going to get the normal clocked 8800. save the 120 for other things.question is: is 120 worth the overclock. in my opinion, no. the 8800 is fast as it is, a 10% overclock is not worth a 15% hike in price, especially with a card as fast as an 8800.
