[build help] need a $4000+ computer for large scale photoshop designing

[aceiswild]

Hello,
I need to design 1000+ sq.ft images @ 300 dpi in photoshop. I am looking to design 10-20+ gb files.. Not looking for lag when I design. -Will I need 64 gb of ram or will 32 be good for no lag? The difference will be $500 for 32gb ram. I am looking for a dual mobo able to get more than 6 ghz.

If you think this is good let me know! or if you can make changes for a better performance pc

My only issue is that I want no lag when I do large scale design. I don't want to wait 20 seconds per click for rendering in photoshop.

Thanks!!

as far as i know..
there's no motherboard for dual ivybrigde socket..

you have to go with the xeon class if you want to using dual processor..

GTX 680 not suit for you, it's for gaming machine..
use vector graphics card like quadro or firegl..

but remember..this combination (fastest xeon and fastest quadro) will burn your wallet into ashes..

64gb..seems plenty enough..i have no experiece with more than 16gb memory before..

agree with quaddro, you'll need a workstation GPU

Can someone write all the parts to what I need. I have experience building a regular pc, a dual workstation processor is a whole new thing for me! I would very much appreciate it!
