Elwood P Dowd's Journal: Video card advice, anyone?

I have this computer. I want to be able to play Oblivion.

I figure I'll have to upgrade my 300 watt power supply so that I can handle a better card. I spent a few hours reading up last night, and it sounded like everyone was suggesting either a Geforce 7600 GT for value or a Geforce 7900 GT if I intend to splurge.

I don't know what ATI cards to look at because everyone seems to be talking about NVidia lately. Don't know why.

If anyone knows the current state of the union, or would like to suggest a different line of cards to look at, I'd really appreciate it. And I know the basics of picking between different cards w/ the same GPU, but if anyone has any advice there that would also be very helpful.

Word up.

Power supply

300W should be more than adequate since you only have one hard drive.

Got a 7900gt in my box

and am pretty happy with it. Lots of rebate deals out there, so if you keep a look out, you should be able to get one for ~230 or so.
