What brand of 4850 should I get?

Visiontek for the lifetime warranty. All of these new cards are basically the same with a different sticker on the front.

EDIT: If you're willing to spend a few more bucks, Sapphire has a 1gb version out, but you'd be better off just putting out for a 4870.

Hmm, Im in Canada btw, and getting it from NCIXHelbrec

You missed by a day their special on the Diamond hd4850 that was selling for 150$ no mail-in-rebate with a free copy of GRID. They had a 100 and it was sold out in less than 24 hours. Check back again next week. At first I wanted an Asus for the 3 year warranty and the fan control software, but they don't have much in stock so the price is high. Diamond has only 1 year warranty but at 150$ I couldn't resist.
