haha you kidding right?? You have to be.
If you using a 5yr old system, how you expect to play anything.
Minimum system requirements for this game are
System: 1 GHz CPU or equivalent
RAM:128 MB RAM
CD-ROM: 4X CD-ROM
Video Memory: 32 MB VRAM
Hard Drive Space: 4000 MB
DirectX: DirectX v9.0
Thats just to play the game, to play at a decent level you require at least twice that.
In a day where most people have over 2gig CPU or equivalent and 128mb video cards.
You best stick to games like Half- Life and other games made 5years ago.
sorry to be brief, but i mean, come on.
