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

Alright, let's see what we've got here:

System Specs:
CPU: Intel Core 2 Extreme QX9650 ( always at 333MHz FSB ) [ QDR1333 ]
Mobo: Asus Striker II Extreme 790i Ultra SLI [ BIOS 0704 ]
RAM: CellShock DDR3-1800 2GB Kit
VGA: Single GeForce 9800GTX 512MB Ref. Card ( Normal Stock Clocks )

Normal RAM Timings: A-A-8-7-6-21-1T-7-35-10-25-35-9-7-74
Tweaked RAM Timings: E-E-7-7-6-21-1T-1-1-5-21-1-1-1-74

Game Settings:
Set 1 = JumpingJack's settings + Default Drivers Settings ( matched with JJs ) @ 1280x960
Set 2 = Real-life gaming settings, Full Details ( All settings maxxed along with 4xAA 8xAF and Transp. Anti-Aliasing ) + Modified Drivers Settings ( see attached pics ) @ 1280x960

As you can see the Snow test is GPU Limited at these settings.
The Cave test is totally CPU Limited.

Memory Performance Chart - "Normal RAM" vs "Tweaked RAM" - JJ's Settings

As expected, the results in the first test ( Snow ) remain totally unchanged since it's totally bound to our GPU's performance, while the performance in the more CPU/System Limited Cave test increased.
