Damn, I need to get a PS3...
The PC version's requirements aren't very high.
Minimum Requirements
Microsoft Windows 7/Vista/XP Intel Pentium Dual-Core T4200 (2×2.0GHz) or AMD equivalent 2GB RAM (Windows 7/XP)/3GB RAM (Windows Vista) NVIDIA GeForce 8800 / ATI Radeon HD 2900 11 GB free hard drive space
Recommended Requirements
Microsoft Windows 7 Intel Core i5 @ 2.66 GHz / AMD Phenom II X4 @ 3.0 GHz 3GB RAM NVIDIA GeForce GTX 460 / ATI Radeon HD 5850 11 GB free hard drive space
If you got at least a decent Dual Core, it should be able to run it smoothly.
I gotta say, I'm looking forward to the myriad of mods that will come out of this. Recolours and pregnant Sonics everywhere.
