Hey, check it out: another GF2 vid card, this one made by SUMA. It's got 64 MB of 5.5 ns memory (as opposed to 4 ns in the Ultra) but it's supposed to cost around $300. Mmmm, tasty!
There's a review in www.tomshardware.com if you want to tease yourself.
If I were spending KBlair's cash, though, I'd go with the Ultra, just because you NEED 64 MB of 4 ns DDR RAM!
