Hello, I've recently built my first PC it's ok i guess for what i spent on it. My specs are an AMD Athlon II dual core 215 processor, an AMD radeon 6870 graphics card and 3 gigs of DDR3 ram. im kinda new to the PC community and was wondering if the CPU i currently have is what you say "bottlenecking" my graphics card since i've noticed while running Dirt 3 i only get 30-40 FPS while racing and 60fps at home screen while on youtube i see similar specs running at 60FPS easy with the same card. my resolution is run really low 1024 X 768 so I know it should be running even better than on youtube. any suggestions?
