Quad core vs dual core

[jamesel]

Hello, below is a comparison of my computer and my friends computer:

Friend:
Intel Q6600 (2.4Ghz)
2GB 600mhz ram
Nvidia 8600GT

Me:
AMD 64x2 4800 (2.5Ghz)
3gb 600mhz ram
Nvidia 8500GT

My problem is i can only play call of duty 4 on minimal settings whilst my friend can play on maximum. Our systems are so very similar my question is how can there be such a big difference in performance?

Thanks in advance

He has more processing cores that makes a difference and it's also down to what the system bus is set and and also wether yours and his ram are dual channel configuration. also if he has a raid 0.

Your CPU retails for about $50, his for about $200... for a CPU a quarter the price, you're lucky to get similar performance. Still, the big kicker is the video card. His has more than twice the throughput of yours.
