I remember reading somewhere there was a high rate of failure on the 8800 series, because of manufacturing defects. The few months after they came out there was a huge hulabaloo over it. I'm assuming that's what happened to mine - it died after 2 years. I have other graphics cards which still work after 10+ years (I have a few old desktops lying around...)
I'm mostly running FSX, so I went with the GTX. A play a few other games too, but won't make a difference with those, really (team fortress 2, steam engine).
I <3 newegg, ordered yesterday, should get it tomorrow

Thanks guys
