Alot of people have the Radeon 6850 with a Pentium Dual Core. But when I put in my Radeon 6850 with my Pentium Dual Core, all games LAG like crazy. How come some people do it, but I can't?

You CANNOT overclock your Dell!!!!!- period. If you had an Asus, Gigabyte... motherboard then you most certainly you could OC. You may want to format your HDD a reinstall just what you want. Clean installs always work better.
