Wish I knew more what I was doing because then I would be able to choose boards/cpu's with ease.

Are the i7 CPU's faster than the Core 2 Quad?

For instance, this Intel Core i7-920 Bloomfield 2.66GHz 4 x 256KB L2 Cache 8MB L3 Cache CPU.

Of course, then I would have to get a board such as this:
GIGABYTE GA-P55A-UD4P LGA 1156 Intel P5...mp; SATA 6 Gb/s

But will those fit in the case listed on that site and is that enough power?

Sheesh...more and more research...
