It's closed because the links don't change between versions.Yeah..thanks pal. I actually went to that thread but it seems that is "closed". So, probably you're right new thread would be created..
The only direct minimum requirement is for a graphics card supporting 'Pixel Shader 3.0'. Beyond that you still need to have a decent PC, but there are no specifications as such.I haven't run the previous CA.. Still do you know it's minimum requirements ?
If you aren't sure, download GPU-Z and run it and then look for the highlighted part, if that says SM3.0 or a higher number you're good in that regard.
