32 gb of ram is gonna be your blocker for iq3, u will have to go iq2 and thus the output will suffer. At the plus side, it will spew faster than iq3.

Iq3xxs fits barely on my 10+64gb, so much that I am agresivelly cashing checkpoints to disk instead of keeping them in memory, moved vision from ram to disk too etc, I am sitting at few gigs left RAM and few hundred MB free on gpu.
