So, I could not get the amount.
I have like 10-12k, can get till 15k.
I have got a new PC, it's a Dell Optiplex 755 SFF. I can shove in all the money. Can you tell me what should I get to upgrade this PC for playing games like COD 4? Currently it has an onboard GMA 3100, not the X3100; the simple 3100. It is Core 2 Duo 2.13 GHz.
