Thanks OP. New low on the 4850, provided you qualify for the 5% coupon---but in my experience, not many people do. I have about 4 Buy.com accounts, none of them accept the coupon.

Nice. I told myself that I'd wait for one 4850s with the bigger coolers on it, but this is tempting. g4u.

wtf? i'm not eligible for the 5% coupon?! i haven't ordered from Buy.com in ages! i meet the conditions of the coupon! ahh, they suck!

i think same card did not work for me

so i used new account, another card

Nice find!

Here's a review link for those interested: ZDNET

Quick summary of the review: Roughly comparable to a GeForce 9800GTX, maybe a little bit slower. Single slot design, so no cooler hanging over one of your valuable computer slots. However, they also report that the card runs very hot, so you may not be able to stick a card in next to it anyway, as you'll need the added ventilation of an empty slot. If your system has good cooling or you jack up the GPU fan(as someone suggested), it probably won't be a problem.

As for me, I'm trying to build a quiet system with very few fans, so I don't think it quite fits the bill. But a big green for the original poster for the great find!
