Probably not. Well, it might just play, but you wont get smooth graphics, it will be a 'slideshow'. Here is the (supposed) minimum requirrements for far cry 2-

• CPU: Pentium 4 3.2 Ghz, Pentium D 2.66 Ghz, AMD Athlon 64 3500+ or better.
  
• RAM: 1 GB
  
• Video card: NVidia 6800 or ATI X1650 or better (Shader Model 3 and 256 MB of graphic memory required).
  
• Media reader: DVD-ROM

You have enough RAM and video card power, but the 2.0Ghz CPU then you have not got the CPU power you need. If it is a AMD Athlon64 (3200+ or 2000Mhz) you may be close, but it will probably not have good performance.
