I'm trying to solve a problem for a friend.
He's Got: a Core2Quad @ 2.4ghz L28mo
a P5K Asus Premium
2x2go of OCZ DDRII
an ATI Radeon HD 3850 and a 3870 in crossfire.
Now he's worried that one of his cards is "dead" because he doesn't get as much Frames per second any more (about 20 fps less).
So he'd like to know if there is a way of being sure of it.
Thank you for your answers.
The only way to test the cards is to try them one at a time. Need to use a program like ATItool and run the artifact checker. If it comes up with artifacts, then its dying. I'd start with the top card, the one with less airflow.
