He say's hes gonna buy another at some point, and didn't say it was SLI. I'm sure he would have mentioned it. If he is going for a third 670 what a waste of money.
This is what I was saying in the other topic.
One top-of-the-line card is enough of an indulgence for most people. Two is a ridiculous for his needs. Three is just burning money.
I can understand the productivity of 2 monitors but again, 3 is over the line.
I mean, its cool that he has so much money to throw at a computer like that (including the power bill) but it is totally needless. Its a big boy toy.
