Your graphics card is what matters the most in gaming and is truly the reason why you can't run games.
Processors get bottlenecked by a shitty GPU and is why most computers with quad cores aren't able to run games at a decent setting and FPS.
At this point though seeing that you have a P4 I strongly suggest you revamp the whole thing and consider rebuilding your computer.
You have a Pentium 4 which uses a 423 socket and is not used by processors used by the powerful processors people have today.
If you have the money I'd look into a LGA1366 mobo such as a sabertooth from Asus, they are reliable and great for gaming.
The i7 is what uses the 1366 and any i7 would have you set for some time.
Dual channel RAM is standard and any higher isn't needed.
Triple channel shows little improvement for gaming :p.
DDR3 RAM is what I would suggest you get.
DDR3 is twice the speed compaired to DDR2 and any higher than 1333 shows next to no improvement.
As for a graphics card a good budget card would be the ATI 6870HD, it goes for under 200 and will be able to run nearly all games at nearly max.
You won't be able to play any current gen video games which is why I suggest you upgrade.
Computer gaming is really costly and before making any purchases do your own research.
Best of luck sir.
