Well this might finally end up as a double post. The first had Bens link to that Sapphire 6670 for $49 and it took it but said in red the Bens Spam filter would qualify it and post if appropriate well its been about 3 hours.

Skip this if you dont absolutely need a single slot and/or have PSU thats 300W or less. The 6670 has you work $5 less on the rebate, a jump in performance, though TDP is 44W for the 6570 vs 66W for the 6670 and why you want a decent 300W PSU.
