Hello guys, i'm new and trying to learn about computers... The issue of choppy play I believe is either the video card or power supply
Video: Radeon HD 6870
Processor: Intel Core 2 Duo? 3.0ghz
Power Supply: 650W
Hard Drive: Western Digital, Not too sure on other specs of it but I know its good I ran a test
If you need more info please let me know I will reply as soon as i get home..
