Vista tells me 5.8/5.9/5.9/5.9/5.9
Core 2 duo E6750 (2.66ghz iirc?), 8800GT 512MB, 4GB ddr2, intel 520 SSD, 6TB of data drives.
Built it in Jan 2008, and other than the SSD and hard drives it's not been touched since. Runs 24/7, reboot it once every 30-40 days, and still on the original Vista install.
Just runs too damn well for me to want to bother upgrading. I don't play any games these days... it's ample for work.
