PC Problems? I am a PC TECH.

Performance question:

I have a home built PC. I'd like to increase its performance with hardware upgrades.

My system has.

Asus M3A78-CM motherboard
AM2, 3GHZ processor (dual core)
4 gigs, DDR 800 memory. (I could add more, but would need a 64bit operating system to utilize it)
Nvidia BFG 9800 video card, PCI Express 2.

BIOS, is set to automatically overclock the processor. It is capable of doing so with this motherboard.

My question is: Would I see much of an increase in performance and speed if I upgraded to a quad core processor? The current motherboard is capable of handling it. I run a lot of games on it.
