Had it a little over a week, but it has been getting a ton of use... not a problem yet. windoze ME, 9009 driver, 1g athlon oc'ed to 1.25.
I have been playing tons of Q3 plus varying amounts of Alice, max payne, RTCW, MOHAA, Tribes2, NFS5... I had to tweek the direct3D settings for some games, but other than that not a hitch.
I have run 3dmark2001 countless times including looped to test my new copper proc sink, and it has never had a problem on it and runs all the games, skipping none.
