Well, I'm running Vista Home Permium 32-bit right now on an EVGA 680i motherboard, C2D E6600, 2 GB Buffalo FireStix PC2-6400, Evga GeForce 8800 GTS 640, Haugpauge TV tuner, and a 250GB hard drive.
At the moment im running a Asus P4SD-LA (HP rebranded stuff) with a socket 478 533 FSB 2.8Ghz Pentium 4,With DDR PC2700 512mb RAM.An AGP ATI 9200 128mb GFX Card with an SBlaster LIVE! Sound card.An SCSI IBm 18gb hdd (Thats has windows XP on it) and then a IDE 80gb Seagate hdd.last but not least a 52x combo drive and a cheap dvd burner.
Sig. Except no water cooling and an X1800XT since the 8900 series isn't out yet. I finally got a crack for Vista that works with 64 bit, so I'll be gradually moving to Vista Ultimate x64 as my main OS now
Updates work and everything. As far as Microsoft knows, I've got a legit version of Vista.
