Have XFX 680i MB, P4-3.0 processor, 500 gig HD, 8 gig RAM, Gforce 8600 video card. Installed windows 7 and it is very awsome and have found it very easy to use. Only problem found is I have a Rocketfish keyboard and mouse Blustooth and seems to loose conectivity often, have to delete and search for the blooth items. Other than that Windows 7 seems to be a very good operating system and look forward to the release.
