KS95 is right, your Intel CPU is fine, but integrated graphics will not run new Racer Betas. As your Dell has PCI-E slot, adding a more powerful video card shouldn't be a problem. Racer generally prefers nVidia offerings over ATI/Radeon and I would recommend nVidia GTX 550 Ti or higher. Just make sure that your PC has power supply that is able to power whatever new video card you get..
