Advice please, upgrading my computer and would like input on what would be compatible, yet not obscenely expense. My ex built several years ago, and still works well but I'd like to upgrade since my focus and usage has changed a bit...not to mention, it's time. Since I game very little these days and my main use is Adobe Illustrator as well as other graphic and plotter software. I'd like to upgrade (if necessary) with more memory, CPU as well as another graphics card. It's my understanding that this board will support multiple devices. Basically I'd like to get the most bang for my buck, and the bucks are limited. 
Specs:
CPU i7 920
6 GB Triple-Channel DDR3 (7-7-7-19)
MSI X58 Platinum (MS-7422)
SyncMaster 1023 MB NVIDIA GeForce GTX 460
913 GB WDC WD 10EALS
APEVIA case (sorry don't know the model type, but should be sufficient space)
Power Supply Corsair GS800
