What is bottlenecking my GTS 250? How do I fix?

I recently bought a new video card: Sparkle GeForce GTS 250 512MB

My friend has a 9800GTX+, running an intel C2D, and gets 12,500 3dmarks in 3dmark 06 These graphics cards are the same, GTS 250 is just a re-branded 9800GTX+
I am only getting 10,500 marks, yet my cpu is clocked from 2.8Ghz to 3.2Ghz.

My system specs are:

Asus M2N-E motherboard (chipset NForce 570)
160GB Seagate IDE hard drive
2 GB (Dual Channel) Kingston ValueRam (2* 1024MB) (667)
Creative- X-fi Xtreme Audio
AMD X2 5400 @ 3.2Ghz 1.55 volts (running stable and cool)
Sparkle GeForce GTS 250 512MB (connected through PCI-Express x16, version 1.0, maybe the old version of PCI-Express bottlenecks my card
Cooler Master 520 PSU

I was running XP home 32bit, and heard a rumor that home edition only uses one core of the CPU at a time, so i installed Pro x64, but this did not help in performance (same 3dmark score and slightly lower frame-rates in games...by like 2 frames) , and only cost me time.

Can anyone help me figure out what is bottlenecking my system, and perhaps how to fix it.

I have quite some knowledge about computers so don't worry about me understanding.

PS: soon (2 weeks) i will be upgrading to 4GB of ram, can anyone tell me id this is going to help?

TY

Post your friends rig as well, and yes the Asus M2N-E uses the old PCI-e interface. Upgrading the memory will maybe give a small ( 100 - 500 points ) boost , but I'm not sure about that.
Furthermore, your processor is getting old as well, it's a pitty you don't have a am2+ motherboard.
Good luck and don't forget your friends rig to post,

Onboard cache? (this may well turn into my new catchphrase).

Friends rig:

Intel C2D 3.0 Ghz
2Gb ram
XFX Nforce 610 Motherboard
9800GTX+
250GB sata HD

Essentially same system except diff brand CPU, and he's getting 2000 more 3dmarks

By the way, my mobo, does support newer quad cores phenom etc. It supports AM2+ CPU's, i just need to update bios.

What do you mean by that?

How much cache on your CPU and how much on your friends?, bear in mind that the two CPU's do not utilise cache in the same way though.

My CPU (x2 5400 @3.2Ghz) has 2 x 512 K
My friends I dont know,
quick google 6MB, but he has an intel, and I use AMD

It's not all about the CPU frequency but more about bus width or bus speed. I don't have any AMD cpus but have you tried to compare your systen on Futuremark's ORB to check if yours is average or below average?

His CPU is just faster, regardless of the OC you have put on yours.

Have you got any spare cache is my catchphrase...well have you?...anything? Just a sniff??

Yes the reason of the higher score is due to the faster cpu and memory (assuming his running 2gb dual channel 800mhz+)

So i need to buy a faster CPU..... from what i hear though it could also be my slow HDD, anyways, any advise on the cheapest CPU to get rid of this bottleneck???

actually this is quite strange, I just realised: My CPU gets a higher CPU score in 3dmark than my friends,

x2 5400 @ 3.2GHz: 2384
C2D 3.0 Ghz: 1847

Don't worry about those numbers play your games and if your not pleased then do upgrade.
