Nice. Go for it! It's a pretty good deal. Even though the FX series cores are starting to become old and can't compete with the newer series, it's still a nice card. Especially BFG Tech and they're Lifetime warranty.
but im still stuck between buying this, or waiting a couple months till the 6600GT AGP is 150ish, since it is much better. im stuck, i really don't know what to do
You should probably wait. It's more economic to wait for the 6600GT to go down in price than spend the money you have on a card that is already breathing its last. This could be some time however. A fair time.
