What do you think about the i7 3770?
I'm unfamiliar with this CPU unfortunately.
and what is so good about ssd's?
Much faster than regular HDDs. Substantial difference in boot and load times.
from what i can see 690's are just for those who want more than one. I mean the differences are virtually nil between 2x680 vs 690. and by me purchasing 680's i can stagger the cost.
If you're worried about cooling, the 690 is a much better way to go. You won't have to deal with the heat between two cards... not to mention the power that two cards would consume compared to the 690.
