GeForce 6600?2GB RAM?Pentium 4 2.0GHz? Recommended ?

the gm saying that the Recommended system requirements is

GeForce 6600 i have amd hd5450 2gb i know its piece of crab but it is better than GeForce 6600

i get about 30 fps in smoke with low settings and 1024x768

2gb ram i have 4 ddr2 i know it is bad too but the game take more than 2 gb about 2.2

Pentium 4 2.0GHz ? i have core 2 duo e8400 its way better than Pentium 4 2.0GHz and i get 100 % cpu usage all the time and get drop fps to 5 every 30 sec

so i think u have to change the recommended to

4 gb ram
gt 610
core i3 530

so that will make sense
