I'm using Win XP Pro and that works fine. I'm wondering if I could run the 64-bit version on my Pentium 4 3.04 Ghz, Hyperthreaded Northwood?1 person got this answerI do too

Ok, I tried this application and it clearly states "CPU number of bits 32" which answers my question. Thank you! And thank you all for your help with this. I'll hold off on the OS until later, when I have my new computer assembled and can test the software I get when I get it. I guess buying a Wii game instead of Win XP Pro-64 bit wasn't such a bad idea... lol

Graphics cards have their own processor.
