AM3 is the processor socket in which your Phenom CPU is made for, once you can run CPU-Z and give us your motherboard information (or just post a screenshot) we will be able to help you find which CPU's are options for you to upgrade too. We will not know for sure which socket type your motherboard has until we get that motherboard information as AM3 CPU's will work with AM3+ motherboards, at this point any suggestions are strictly speculation.
As for your RAM and GPU, you will not need to replace them but you might want to later on down the road after getting a better processor as once you clear one bottleneck another one usually will form unless your running a well optimized system.
i hope my system is optimized, i was considering getting more ram, but i think a cpu will be more beneficial first to see what happens.
i do know i have 8gb of ram crosair i beleive they are ddr3, and for graphics cards i have 2 AMD Radeon HD 6800 in cross fire mode, both 1gb gddr5 each. i have posted below the system information from another post a few weeks ago.
