Im making a build right now, and i was going for tri sli/tri fire. Which scales better, when using 670's,680's,or 7970's?
The 7970 would be the Asus Matrix Platinum, and the 680 would be the direct cuII top
Crossfire scales better, but you're not going to need that much graphics horsepower unless you're going to be running multiple monitors, gaming in 3D, or both.
I hope you're water cooling them btw, because if you're not at least one card is going to overheat.
