Pentium Dual core OC'd and Core 2 Duo gaming

Which would be better, A Pentium Dual Core 2.2 GHz OC'ed to 2.93 GHz OR a Core 2 Duo @ 3.0 GHz

I am currently using the Pentium Dual Core @ 2.2 and i want to know was kind of gain i would get from the Duo

I know there are forums out there that compare but none really answer my question

Also i game, mainly COD4 and i notice that in grassy areas(pipeline) the FPS gets low round 30 FPS...i think my Graphics card is good enough(MSI 9600 GT OCed) the game is a everything max 1680*1050 4x AA anisotropic filtering at max and i usually get 80 FPS..could this be a processor issue?

Thanks

so your saying its the video card being weak....what about the processor comparison

Clock the pentium to 3.0 and the only difference is cache. Not that big of a deal. Cache is in MB and a MB is that much info anyhow.

I think u need at least 3.2~3.3GHz to be equal with that C2D in some certain areas
3.5+ to outperform it
but don't forget C2D can OC as well

9600GT is a decent card for 1440x900 (19" ) but don't really cut when it goes up to 1680x1050.

I'm using dual 9600GT and I'm not satisfied at 1600x1200 all maxed and AA and AF enable in some certain titles like mass effect and the last remnant when in fighting scene, it drops to somewhere 18~24fps

i know this isnt a vid card thread but what about these paired up

the 9800GTX+ with the E8400

will those work well together?
