I am building my own computer I am just wondering how much difference i Will Notice over what I currently have. I have an older EmachinesT3422 to be exaxct with 2 gigs of ram and a raedon 4700 pro video card. I am getting the EVGA X58 SLI LE Motherboard, the intel core i7 860 processor, the Sapphire Radeon HD 5850 1GB GDDR5 Video Card, and 6 gigs of ram. Am I going to notice alot of difference while playing games or will it be not real noticible? I currenty am playing modern warfare 2 and it runs smooth and seems good, thats why I ask if I will see alot of difference or should I save money and not build such a powerful system? Thanks!
