Holy wow. I'm sure Signburst is a great company and all but...I mean...I literally just built a new i7 4.4ghz desktop for one of my office employees on Amazon 5 minutes ago and it was less expensive than their bottom of the line i3 3.4 Flare.
I know you want something off the shelf but you're going to waste a massive amount of money buying a pre-built high end
computer.
The below build was less than $1300 on Amazon. I have nearly the identical build on this PC but with 32gb of Ram and a better video card. It starts up in 12 seconds and loads photoshop, illustrator (or any addobe app) and Versaworks instantly. You don't even need a $200 graphics card either. The integrated graphics in the 4790 is sufficient for most everything besides 3d modeling (which we're doing) and gaming.
Pay some geek squad nerd $200 to put them together and you're still coming out a few thousands ahead.
