Is this even worth getting on the PC, or should I wait until I own a PS3?
I own the PS3 version, played up just passed Quelagg (in blighttown), the PC version is so much better in my opinion due to the consistent framerate and high resolution. I've played through the PC version about 4 times now.
That's all assuming you have a half decent PC. My nephew was playing on a 9800GT and a dual core AMD, probably 4800. He was having issues. But my other nephew was on a 9800GT and a 3 core AMD at 3.2ghz I think, and he wasn't having issues. So make sure your CPU isn't a dual core PoS.
Don't lie to someone who trusts you. Don't trust someone who lies to you.
