Graphic Card Problem- Fps?

[Pnin]

Okay. I bought HD 4850 few days ago. I Put it in my pc, all stuff works great.
Started to play cod2, wtf 80 fps max! (maxfps 125, i look in the air)
I asked some friend an he told me i have to install latest drivers.
I did that. Went in the game..Same!!!! (btw settings are minimum)

Do you know why?
I have some reasons: Maybe because my motherboard and proc is too low (athlon64 3200+, asrock 939s56)
The card is Pci-Express 2.0, I have only Pci-Express?
Card slowed pc a lot
Is there any solution what do u think?
It will be better if i buy Quad core 2,5 ghz and some cool motherboard?

What fps do you get in better games?

I'll tell you.

POOOOOOOOOOOR!
Cod 4 normal playing at Crossfire, omfg 10 fps max....Really bad. 20 fps if i look in the air....
Proc and motherboard,right?

Probably processor, yes. I am trying my hardest to refrain from the comment I would normally make to someone in your position

The card is Pci-Express 2.0, I have only Pci-Express?

I just noticed, I'm no tech-head, but that surely is going to be a problem.

That should not cause any issues

We took an ATI Radeon HD3850 mainstream card and an Nvidia GeForce 9800 GX2 dual GPU high end board and limited their PCI Express 2.0 interfaces to x8, x4 and x1 link speeds in an effort to find out whether or not PCI Express 2.0 is really necessary to achieve the expected performance. Regardless of the outcome, PCI Express 2.0 does have one major advantage: new PCIe 2.0 graphics cards are compatible with PCIe 1.1 motherboards, meaning that they will run on them using the available bandwidth of PCI Express 1.1.

And if that isn't enough proof, here are many people confirming it works on your exact card.

Ye card works at 1.1
athlon64 3200+ is not really new thing
