My computer is having performance issues. Can you help identify why?

My computer is a monstrous cross between home built and pre-built components. I bought it from Dell years ago and have been upgraded almost everything except the motherboard and cpu.

Anyways, I have been gaming and I have noticed horrible performance in games. Team Fortress 2 now operates usually below 15 frames per second. New games such as Battlefield: Bad Company 2 and APB are unplayable. Every one of those games, I beat the system requirements, yet I still have issues. I know that it is a hardware issue considering that the performance maintains its deplorable state even when I reformat my computer.

I can't seem to wrap my head around what is causing these issues. If you guys could identify what I could do to solve the problem, I would love you forever! Thank you!

Also, I apologize ahead of time if this is not the correct place that I am supposed to be posting.

Update drivers, check for faulty hardware aka. take every major component out and try it out on another machine; begin with ram, gpu and the psu.

The processor is your killer.
The Pentium D 930 may be a 'dual core' don't be fooled by the speed or claim it is dual core. If a game is talking about a requirement for dual core processor, they are refering to much better dual cores.

That CPU is holding you back - in fact it would probably bottleneck a 3850 nevermind a 5850.

Time to replace, mobo, RAM and CPU for performance in modern games

He's absolutely right. Your CPU is holding you back.

I would say its a processor problem but you are saying battlefield bad company 2 isnt playable at all, this game doesnt need that hardcore processor, also ram is very bad DDR2 533, I dont think its only the processor problem its the overall computer, it needs replacement, ofc keep the VGA its great :)

Actually thats wrong Smile9999. Battlefield Bad Company 2 is one of the few games to utilize all 4 cores of a Quad Core CPU.

In the case of the Dual Core, yes it most certainly will lag.

Yes, a good dual core will run it well, however the Pentium D is nothing like core 2 duo or i3/i5 dual cores which are fast and efficient, the Pentium D was one of the early attempts, it's like 2 Pentium 4s (chips already considered too hot and inefficient) stuck together.

Afraid the OP needs to discard the core of his machine - replace the CPU and mobo - and therefore the RAM (assuming he goes with modern technology)

Hmmm, this definietly shows how little I know about processors. I was debating if I should rebuild my entire computer or just get a new processor. I think I'll just do a new build (aside from the hard drive and graphics card, of course).
