I noticed the requirement for MW3 for AMD CPU is a Phenom.. Mine is only Athlon X3 440. But hey, the Intel requirement says 2.40ghz and I have a processor at 3.0ghz triple core.
I can definitely play Black Ops with my specs, I wonder if it can run MW3. Please don't post answers like, "go to this website..CanYouRunIt.com if you can run it". That website is a lie.. I have a friend who has a Dual Core CPU @2.80 ghz and a Sapphire 4650 1GB and he can run Black Ops without issues.
You may notice I have a weak graphics card but I'm gonna upgrade it to a 4670 soon. And about the requirement, will it run fine on my Athlon X3 440? I can run Black Ops, which pretty much has the same system requirement for Modern Warfare 3.
COD games aren't demanding. And we can expect this one to be less demanding as well since the game used the same engine since COD4 with some modifications made to it.
You can run the game okay, but not maxed out as your GPU is a slowing factor.
