What Operating System do you use?

I have XP on this one, will have 7/64 and some version of Linux dual boot on my new system when it's put together. Waiting for a new cpu now, the first one was DOA...
 
Ya, set me back by another week (return DOA cpu/wait for replacement to arrive) to get my new system running. It was an Athlon II triple core, makes me wonder if I should have gone with Intel instead.
 
The motherboard is an Asus M4A785-M. It will unlock a 4th core, but 3 cores are enough for me for a few years. When the games are built on 4 cores instead of 2 I'll upgrade to a 6 core cpu. By then the price will be lower anyway...
 
MAC FTW! Made my computer from scratch and it's a fricken machine. 12 core processing, 16 gig ram, liquid cooling, 27" screen, and 3 graphics cards all built into a Mac pro case.

Hackintosh or just a mac case? What would a mac user need all that power for, cant game on them, unless you play wow and thats way too much power for that. haha
 
oh btw, using Win7 on my desktops and HTPC, ubuntu on my laptops.
