I am looking at upgrading my CPU on my computer and would welcome some advice if its worth it, or just to stay with the one I have. Existing System. AMD Athlon II x640 3.oo Ghz processor. 8 gb ram AMD Radeon HD 7700 graphics board AMD Radeon Asus M5A 78L-M LX V2 motherboard ASUS - Motherboards- ASUS M5A78L-M LX V2 My new addiction is going to be Planetside 2...a MMO shooter, with hundreds of people scooting about on screen at a time, it is going to be quite a load on most computers....My system is ok at the moment while playing this on Beta, and it is pretty damn good on almost all my other games. Is there an affordable upgrade route or is it going to be expensive ?
