I'm starting a new thread, continuing a partial I began on Joan's, looking for suggestions from all you computer savvy musicians to help me find a new desktop computer.
I already have a laptop and need the large dual monitor support provided by a desktop.

I'm replacing a 9 yr old Dell Dimension 8400 with 3.25 (4)GB RAM, Sound Blaster Audigy 2THX sound card and ATI Radeon X300 video card with (DVI/VGA/TV out)

Need one with the following requirements:

Must be a desktop.
I already have a laptop and need the large dual monitor support provided by a desktop.

Good sound output for BIAB/ Realband use.
I currently have a Toneport UX1 with Yamaha Midi keyboard, You Rock Guitar/Midi COntroller, Yamaha and Ovation guitars and mics running through it.

Good support for Photoshop use.
I do a lot of illustration work in Photoshop which is RAM intensive.

Dual monitor and 1080 HD TV outputs,support.
I currently use my 42" HD LED TV as a second monitor and may get a 3D version someday.
Also watch streaming videos but do not play video games.

Good reliability.

Now here's the hard part.

My budget is only in the $600-$1000 range, the closer to the lower end the better.
Looking for the most bang for the buck.

Any suggestions to this "you must be dreamin !" computer will be greatly appreciated.
Thanks,
Carkins
