Well since there's no sticky, then just create a thread

(like you just did, just rename the title to "need a $300 graphics card")
Next thing people are gonna ask you is when do you need it.
Only reason is G80 is coming out (supposedly this week) so if you wait a week or two, you might be able to get some price cuts on the 7900's and X1950 series cards.
I would say the best card for that money is this:

It's the 7900GTO from evga. It's OOS and I don't know when and if it will come back but if it does, it's a really good value.
(is it coming back?)
