Okay, I was wrong... it's just a regular BFG 6600 card with 128mb ram. model # is BFGO6600HSX. Weird thing is, I forgot I had two of them running in SLI mode... thought I gave one to Tom or something.
Looks like your card is also SLI compatible, so if I wanted an extra kick, I could pick up a matching card off ebay or whatnot.
Anywho... if you're interested in one, you can have them both, and run 4 monitor off one PC. lol Or just have a backup.
