Upgrade from 6600 128mb

[Madmuazel]

I'm currently in the market for a new Video card.
I'm just interested in some input.

I have a 350watt supply right now.
Just looking for 1 good card.
My Frames dropped a bit when I uped the resolution
to fit my 19" LCD's Native.

Been thinking about 7600 or 7800 currently
no very solid opinion on it right now.

Thanks
