My Gigabyte Radeon 4870x2 has served me well for over a year now but a few weeks back a rash of green pixels appeared all over the screen, this was followed by flickering groups of pixels and jagged artefacts on 3D models, coupled with frequent lockups, BSODs and CTDs of course. The problem has gradually progressed from mildly annoying to completely unusable. This is without any overclock and with the latest drivers.
My research leads me to believe that the most likely cause is bad graphics memory. The upside is that it looks like the card is still under warranty, however, sending it back leaves me without a working PC for several weeks.
So maybe I buy a new card before I send this one back, then maybe I can sell the replacement to help pay towards the upgrade.
The question is what card to get, the 5870 seems like a decent bet as i could get another one to crossfire later down the line when i rebuild my system.
On the other hand I'm not too happy with ATi as of late due to my currently dying card and some previous driver hiccups, with the availability of the 5870's really pushing the price up, the GTX 295 is an option.
Is the most likely explanation that my 4870x2 is dying?
Overheating did cross my mind, this card always did run really really hot, I took the card out but it didnt seem that dusty, but there is no way I can properly see or clean it without removing the cooler from it, and if I do that then I can forget about the warranty
