Obviously this isn't as hot as the deal ZZF was running earlier, where you could pick one of these up for $250 but even at $300 this deal is better than lukewarm, I'd say it's warm to mildly hot.
Of note is the fact that while this card doesn't have SM3 like the GF 6XXX, and 7XXX series of cards it runs all games except for Doom3, and The Chronicle's of Riddick Noticeably better than a 6800 Ultra, and this is at a 6800GT price. So if you play CS:Source, or Battlefield 2 this is a much better buy than a 6800GT, or Ultra.
Also of note is that ATI will be releasing it's "Crossfire" master cards, and you'll be able to "SLI" this card with one of the Crossfire x850XT, x800XT, and x800XL, master cards, and get a performance increase simmilar to an nvidia SLI setup. Rumor has it(so this is subject to change) that you'll even be able to SLI them on an nForce 4 SLI mobo.
Good find OP
