ok, this is probably the question from hell, but please bear with me 
Until recently i was using a sapphire 3850 agp card in my pc, never had any crashes, not one.
I got hold of modern warfare 2 and decided that i should upgrade my system to a newer pci-e card whilst my old card was still worth something on ebay.
I bought a sapphire radeon 4890 pci-e card and fitted it. all was well, the games performance was really, really good. I sold the 3850, all was well.
Then the problems started, i started to get random crashes during modern warfare 2 during multiplayer mode, and when i returned to the desktop (windows vista sp2) i had a warnign message waiting for me staing that the display driver had stopped responding and had recovered.
I did some voltage mesurements using a calibrated multi meter and removed the sides from my pc. i was noticing voltage flucuations on the 12v rail, so i begrudgingly purchased a new psu (antec ea-650).
Voltage flucations disapeared all was well, for about 20 minutes until it did it again.
At this point i lost my rag and arranged to return this card and get a refund. as a stop gap measure i have fitted my backup card (nvidia 6600 gt) and have been (for a laugh) playing modern warfare 2 at 1080 resolution with no crashes, no nothing. Not laughing anymore.
I am coming to the conclusion that the 4890 was a dog, and am in the market for a new graphics card that can play games like modern warfare2 and team fortress 2 at a resolution of 1280x1040 with a decent quality with NO crashes garaunteed.
If such a thing exists can someone let me know as the last thing i want is to have another dog on my hands.
cheers,
rob
