same...it i had to look at them for a bit to but I got them all right. I wonder what kind of hardware you need to run these smoothly

CPU: Dual-core CPU (Athlon X2/Pentium D)
Graphics: Nvidia 7800GTX/ATI X1800XT (SM 3.0) or DX10 equivalent
RAM: 1.5Gb
HDD: 6GB
Internet: 512k+ (128k+ upstream)
Optical Drive: DVD
Software: DX10 with Windows Vista

The really noticeable piece here is the RAM -- I'd bet that recommendation is probably the reason why the PS3/360 can't run this game on full detail.
