true, we've drifted off topic somewhat.
I'm still waiting for an RMA # from Sapphire/Althon tech, but they will replace it as some others have noted as well.
Yet, I think I may just keep mine. It's a 2slot card, 1.6ns memory, runs pretty cool at load (~63c) with a mild 563/617 OC with the stock cooling fan at about 40% (any louder and I can't take it). With the Arctic Silencer running full tilt, it'll likely do better.
I feel like i've gotten a decent card here for my $139usd, and don't really want to take the chance of getting a "real" replacement x850XT that doesn't spec as well. WHich, I believe, is a distinct possibility.
Mainly, the card stays cool. Cool card = better chance at longevity. I've had ATI cards for a while now, and my 9800xt was absurd - even with an Arctic Silencer on it I could barely keep it under 85c load. And that was the one I got after RMA the first which got just as hot.
