new SSD, and I had already upgraded to win8 directly from win xp...can I go from win xp to win 8 without win7? It's a clean new SSD, in an existing system. I have a WIN NT pro also I could use and WIN XP Pro full
Yes you can upgrade from XP, Vista, or Win 7, to Windows 8.
If your motherboard is 64-bit capable then you can upgrade to 64-bit Win 8. I upgraded two Vista computers to Win 8; one was 64-bit capable so I upgraded to 64-bit - the other motherboard (and CPU) was just 32-bit so I could only upgrade to 32-bit.
