So, what do you think would be a good idea:
A.) Wait for Windows 10 to release, and then build my new PC. Hardware could change, so I might make adjustments to my part list if this happens.
B.) Get Windows 7/8 and build it NOW, but upgrade to Windows 10 when it releases.
I've pretty much got the parts locked down, might make some adjustments. Now it's a matter of "Do I really want to do this now, or wait?"
