So I have a geniune copy of 64 bit Windows 7 Pro, and am going to format my computer and install it. What should I do out of the two options I have: 1. Get the second 500GB 7200.12 I got downstairs, RAID it with my current one and install W7 2. Get the five 160GB 7200.10's I got downstairs, RAID them all and install W7. This requires me to swap out my HD4850 with the 4830 I got tho, due to case limitations. I will prob get a new case and crossfire the 4830 and 4850. But im not really fussed on graphics atm, just want speeeeeeeeeeeeed lol.
