@muraii yeah, as far as I know you're stuck with CC. At this point unfortunately Adobe is doing its best to funnel all photoshop users towards it–reselling is illegal I think, & they've stopped selling CS6 entirely...so it's subscription or the pirate's life. :s
I'm still using an old university copy of CS5 for now, but I'm thinking that the most sensible way forward long term might be to buckle down & try to learn some open source programs.
Gimp is pretty painful for digital painting. It's more helpful if you're trying to emulate old Photoshop tutorials for creating game art.
@muraii FWIW my wacom works great with GIMP and even better with krita!
