As stated above have a EVGA GTX 275 896mb version. It has been very slightly overclocked only for the past two months, it has never been overvolted.
I'm asking ~90$ in bitcoins.
The other card is a BFG GTX 260 core 216. Had an overclock only while gaming, never overvolted.
Asking ~60$ in bitcoins.
Neither card has ever crashed or had artifacts while gaming. Well taken care of never run 24/7.
I have had one successful trade on here: https://bitcointalk.org/index.php?topic=61696.0
