A friend of mine has a Sapphire HD5670 512MB and wouldn't mind trading it for my Gigabyte GF9600GT with a passive cooler since the HD5670 doesn't have analog TV output and he needs it. I sure don't mind since the HD5670 is a notch faster than the 9600GT and eats less power. Now I'm thinking of picking up another Sapphire HD5670 512MB on the cheap and running a pair in crossfire. Normally I'd never do that, since a single HD5770 would make more sense, but here one of the cards exists already and it would be a rather cheap performance upgrade for my 2nd rig which runs a 1680x1050 monitor. Would you crossfire HD5670s if you were in my shoes ?
