Okay, I've gotten some helpful responses here, done a bunch more research, and made a raft of changes to this system, bumping it up to 32gb DDR3 1600 ram, among other things. Also opted for a xeon CPU since I've no plans to overclock and can use the $ elsewhere to stay within my $1,500 budget. You can check out the details
HERE (note this configuration still shows the i7 3770 CPU as the Xeon doesn't seem to be an available option on PCpartpicker).
Haven't pulled the trigger yet, so feel free to weigh in with opinions. (Also feel free to just tell me it looks good, too: this is my first build and I could use the confidence boost!)
Some notes:
Xeon E3-1230 V2 -- Virtually identical to i7 chip in performance but less expensive as it lacks internal graphics (unnecessary with dedicated GPU)
Geforce GTX 660 -- In CS6 Photoshop-specific benchmarks (
here) it performs neck and neck with more expensive cards.
Asus P8H77 mobo -- supports LGA 1155 and SATA 6gb/s that I need, but saves money by not supporting overclocking which I don't need
Crucial RAM -- trusted name, runs at a lower voltage so maybe a bit cooler
So that's where I am. Thoughts?
