Never had to redirect temp folders /shrug My setup is fairly simple, 3x 500GB SATA HDDs and a another 500GB external, 1 is partitioned in 3 for the OS, Photoshop scratch disk, and program files. The other two are mainly storage and the external I lug around so I can look cool at the cafe even though I can't stand coffee, lol joking but the external just so handy.

Hey more RAM can't hurt (in most cases) looking at the clock and bit rate, 1GB DDR3 seems good to me, though 2GB I think will lessen the possibility of bottlenecking and thus viewport lag. I am by no means an expert on this but its just my 2 cents.
