Was wondering if some of ya can help and tell me if my PC can run CS:GO, or if I need to upgrade it.

Computer Specs:

>Pentium(R) Dual-Core CPU E5200 @ 2.5 Ghz
>4.00 GB Ram
>NVIDIA GeForce GT 240
>Windows 7 64-Bit

If you need anymore information please don't hesitate to ask.
Thanks in advance for any useful tips/opinions.
