CoD Modern Warfare 2 x64

Hello everyone!

I can't decide what to purchace!!!

32 or 64 bit win7.

I mainly play games and I've a pretty new PC, I'll give you the information about it to make ur advice easier:
Sapphire Radeon HD 5850 1GB GDDR5
ASUS P7P55D PRO P55 S-1156 ATX
INTEL CORE I5 750 2.66GHZ 8MB S-1156
CORSAIR 4GB DDR3 XMS3 INTEL I5/I7 DOMINATOR 1600MHZ CL8 (2X2GB)
SAMSUNG SPINPOINT F1 1TB SATA/300 7200RPM 32MB

So will 64 bit be a better choice for me, give me better performances when playing game and perhaps, better help for my Grapic Card? if compared to the 32bit version??
thanks in advance!

As you've got 4GB of RAM and a good system, it's a no brainer to go with x64 I run COD MW2 on a 64 bit machine and it flies.

No point in running 32-bit on a PC like that

okey

Thanks alot for the quick response!

4 GIGS and above need a 64 bit operating system.
