GPU is underpowered for the processor as you've already heard, but my question is your drive config... Is there any particular reason you are running 2 different 7200rpm HDDs as well as a 120gb SSD when you already have the 500gb for the OS? Also, not sure how you feel about RAID, but I find myself having to use it frequently at my local technical center due to us having no SSDs but still wanting decent performance. Now, I know RAID 0 is bad because you lose your data in the event of a failure, but I have (so far) only had 1 "RAID 0" array (was RAID 10, but not sure which drive ate it) die on me (and it was from adding a sketchy GTX 680 to the PC.)
