Just built a new computer for making art. (Old system had numerous hardware issues and has consequently been demoted to HTPC status).
Processor: intel i7 2600K
MoBo: MSI GD-65 Z68
RAM: 16GB Corsair Vengeance
System Drive: OCZ Vertex 3
Storage Drive: 2x WD 2TB greens in a RAID1
Video: Sapphire 6950 2GB
Yeah, it's really overkill for what I need, but it should last a while. Now I just have to hope that life in general calms down enough that I have some time to get back to being an artist.
