A computer for graphic art

[321cartoons]

Hi,

I am new here, so I don't know where to go with this.

I need help building a computer. I won't buy it yet, but I think instead of buying and iMac I should build a computer to my needs.

I'm on an $800 budget. Can't go any higher.

I need a desktop that can handle Adobe Flash CS6, illustrator CS6, Photoshop CS6, and After Effects. A little web browsing and spotify. I also will be hooking up a wacom cintiq 13HD to it, so I will need an HDMI port.

Thanks!

Also, can you build all in one computer's?
