So 4 days ago I got this killer Gaming PC off of Ebay and it's really nice but I can't seem run my favorite game Call of Duty Black Ops very well. I know they did a large overhaul on the CoD engine but if my xbox can play this shouldn't my PC? I paid roughly $1800 for the PC, It has Pentium II Intel processor which the guy told me was a little old but he unlocked and overclocked it for me. I'm not sure what that means but the guy knew what he was talking about. It also came with a 10gb hard drive which he said would hold all my pictures and games. I'm not sure how much ram I have but I know he hook me up with a lot. PA-2013 Motherboard and a 1.44 mb storage floppy drive which comes standard with all of his higher build PC's. I also noticed that it didn't come with a case so for right now I'm using the cardboard box that shipped it. I tried calling the guy's phone number but it's unavailable so I'll try calling back later. But if anyone has any suggestions on how I can get CoD to work it would be most appreciated. Thanks!
