Why does phenom perform better than an intel quad at high resolution in Lost Planet?

[DIE-TEMP]

I own both a Phenom 9500 rig and a Q6600. My AMD is clocked to 2800mhz for 24/7 use with 2GB of DDR2-1000.
My INTEL is clocked to 3400mhz for 24/7 use again with 2GB of DDR2-1000.

both rigs have an 8800GT 512MB and run off 250GB sata HDD's.

When it comes to 3D MARK 06, the INTEL scores 17k the AMD scores 14.5k.

When it comes to Super Pi the INTEL computes 1M in 13.2secs whilst the AMD computes 1M in 23-24secs.

No brainer picking the benchmark winner there.

For multi-tasking with resource hungry apps the AMD rig runs smoother no doubt.

There's an easy experiment which users can try which will show what I mean.

Download an app call WALLMASTER. It's designed to change your wallpaper automatically every 1-100minutes (user selectable).
Install this tiny app and select 10 wallpapers from your fav backgrounds and set the app to switch desktops every 1minute. Once you have setup wallmaster and have it running, fire up your fav 3D game.

INTEL users will experience severe stuttering ingame each and everytime wallmaster loads a different wallpaper. AMD users will experience no such effect.

IMO both cpu's have their advantages over each other. I do believe however that AMD have a "smoother" feel to them as a result of decreased latency and an IMC.
