I post from my iPad most of the time so forgive the typos!
Running RS14 on PS3 and on Macbook:

Intel HD Graphics 4000 384MB - built in
Nvidia GT 650 512mb
PRS Santana SE - modded with EMG 81/85 active pups, locking tuners, Tremol-NO
PRS SE 245
Gibson Les Paul Traditional Plus - classic 57 pups
Gibson 1941 J-35

mxr smart gate
crybaby 535q wah
I didn't much like the iRig, either, so I bought the Ampkit cable. I've also got Ampkit and Garage Band waiting to try out, but RS has been taking all my guitar time.
