Art Computer: Critique My Build

[bkh2]

Components:

Mobo: Gigabyte GA-890GPA-UD3H
CPU: Phenom II X6 1055T
PSU: Antec 650W
RAM: OCZ Gold 1600MHz 4GB DDR3
GPU: Radeon 5750
Case: Thermaltake V3
HDD: WDC 1TB Black
ODD: Ghetto

These are the things that will be done on this computer:

Digital painting
3D modelling/texturing
Record videos
View/play videos
Play music

Programs:

photoshop cs2 and up
ToonBoom
3DS Max
Windows Media player
Possibly Adobe Premier

I'm trying to minimize cost while getting good performance for the specified applications. Let me know if I should change anything.

It looks good, you'd obviously get more performance from a 1366 system but seeing as you want to minimze the cost getting the most amount of cores/threads possible is a key/important thing as a lof of that 3D modeling/texturing is done by both the graphics card as well as the processor as well (especially if you're looking into detailing in 2D/3D)

Thanks for the input, Arinoth. I'm also concerned about the GPU. Will a 5750 suffice for these applications? Would I even be able to go with something less, like a 5650?
