Desktop build for a photographer

A couple of weeks ago I posted a message about building a new desktop computer for my photography needs. Since then I've done lots of research but I'm still looking for input. So, let me make this a little simpler.

If you were building a new desktop to handle your photographic needs (semi-pro) what would you include in the way of a motherboard, cpu, video card and Ram. Intel seems to be having some issues getting out it's newest cpu's and those promised for this month are doubtful so my time frame for a build is in the next 30-60 days. Budget for the machine is around $2500 (not including monitors) and the video card should be able to (eventually) push dual moitors one of which may be 2560 x 1440.

So, what would you include?

Sony F505(retired), Sony F707(gave to son), Sony
F717(gave to wife) Sony S85(great little camera that
was stolen), Sony CD 1000 (ancient but a great lens), Sony P93
Sony H9(retired) Panasonic LX3 that became an LX5 (small
enough to go everywhere), Nikon D5000 that grew into a D7000, Sony HX1, Pany GH2
