I love the game Black Ops...I believe I will be the 1st on the map,with this system but my real reason for this eccentric build, is before I had a laptop and was playing on that...... But I seemed to be lagging and I knew that a laptop was not going to make the grade in this game....I built my son a computer and it's specs are not quite up to mine but still pretty good, His games are fast, smooth and accurate...so I'm thinking that if you put a lot of effort in the system you should get results, and it's not really the internet that makes you die a lot..... what do you guys think?
