Is that a good thing or a bad thing?
Mine would probably be dead now too, except I seem to have a knack for carefully and successfully taking things apart for maintenance and such. My card fan would have burnt out long ago if I hadn't discovered that regular car motor oil works just fine as long-lasting lubricant on it. (I wanna say 5W-30?) Plus, when I replaced my thermal paste on my CPU (and got a non-stock cooler), I opted to do the same on the graphics card, and it's been running smoothly.
Though my definition of "smoothly" is non-stuttering 30+ FPS, whereas the newer definition seems more like 60-220 FPS, so...it won't win any sprints but it will go the distance?
Honestly, I'd probably be happy with a 760/80, maybe 9 series - I dunno if I want to go with x50 card again, even a ti.
Also, do you have $125 to spare, too? [money]
Oooh, that would be fun...at least if I could get all the compatible hardware...!
