I am planning my next PC
Since I got PS3, PC gaming will not be the purpose of my new computer(well, occasionally a nice pc game does no harm

). So, I would be very glad if I can watch AVCHD smoothly on the pc, and a fast software such as photoshop to deal with pictures or NLE to handle video would be great.
There are lots of options
Nvidia GeForce 8 series? but I don't really want DX 10 anyway...
GF 7 series then?
What about ATI? X1950 looks good and not expensive...
But new HD2900? is it better on HD output?
Nvidia Quadro FX series? FX1500 is affordable, but is it really much better on NLE? what about 2D application such as photoshop? and back to game, is it good to play a 3D game? (oh I am sorry I should not have asked this one...

but just for curiosity)
Nvidia SLI/ATI Crossfire? Oh no that's for gaming...
Anyway I will focus on photography/video processing, as well as some sound/music software, and I can't resist nice pc game. (I think a graphic card which is good for NLE should be powerful in every aspects anyway...)
So which graphic card should I get?
Thanks!
