alright i see i see. im not that smart with all this stuff but if i added a video card to the lano would i get better performance than with the phenom witha gpu. also. Aastii how would i be able to change how would i be able to change it
It would depend on what you used the system for. If you plan on your system being there just for "home" use, by which I mean using the internet, watching videos, listening to music, using office applications etc, there will be no performance increase. If that is all you will use it for, you are better off with neither CPU, and instead going for either an Athlon II x2, or an Intel i3.
If, however, you plan on gaming, you will not just find a graphics card will give you better performance, you will find it is essential. The Phenom II would also perform a lot better in games than the A8 would.
As to how you would raise the multiplier, it differs between different motherboards. The basics though is go into the BIOS at bootup (usually press Del, or an F key at boot up to access it) and there will be overclocking settings where you can manually set the multiplier. You would ismply set it to 17, rather than the stock 16 of a 955, and you would have a 3.4GHz CPU, identical to a 965
