DEll,Video card,power question

[happy medium]

The power supply for my dell is 250 watts. My question is, what nividia card would work in this system as far as power consumtion is concerned . Also considering my cpu speed[ 3.06] , bus speed [533] I don't want to bottleneck my system.I have a mx 420 now and it sucks .

That power supply is ok, but dells psu are garbage from my experience. But you should be able to pull of a midrange FX series. Id go for a 9700 pro or something though.

I was hoping to try a 6800 nu since I don't have many components to power. Anyone know of any aftermarket power supplys that will fit in this rig?
