I greatly appreciate the help I've received so far.
Anyways based on Outlander's advice I've decided to buy an entirely new computer and after looking around some more I've found another computer that may better fit my needs than the one I previously posted. The computer can be found at the following link http://www.newegg.com/Product/Product.aspx?Item=N82E16883229283
I would like to know if this computer is capable of running modern games on high graphics and if it is a good value for my money, especially when compared to the Budget Intel-Based Gaming PC in the link bobusboy posted. However please take note that I would rather buy a prebuilt computer than build one myself.
