Its SO much better on pc if you have the hardware. Played the ps3 version at a friends and while not normally a graphics whore, having played it on pc near maxed out at 45+ fps then going to that made me feel bad.
Base game for $7.50 is worth it if your PC can run it well.
Definitely recommend installing Ziggy's mod. Fixes a lot of issues that people had with the base game itself (Difficulty curve, crafting recipes, weapon modifications, etc.). I believe Ziggy's forces the game to run in DX11 IIRC so keep that in mind.
