Done some quick benchmarks with FRAPS, This is interesting.
I got my i5 to a quick 3.6GHz O/C (No Turbo) so the benchmark is unbalanced straight away in favour of the dual core.
Here are a few screenshots of the i5 @ 3.6GHz - HD5850 @1000/1200
All settings = Medium in game (Settings below) the same as what i ran some tests with the dual core.
Some average FPS results with the E8400 @4.1GHz - HD5850 @ 1000/1200
All settings = Medium.
Ingame settings:
=================================

=================================
Notice with the quad core, The GPU is flat out, Even at just 3.6GHz.
The GPU ran around 60% with the dual core @ 4.1GHz.
I will do some more tests when i get her stable around 4 GHz.
Going by this, I have seen around 40 FPS increase with a quad at 500MHz lower clock speed.
Feel free to point out any mistakes here, I am no expert at this
EDIT:
i5 @ 4.2GHz GPU @ 1000/1200 Ingame settings = Medium.
Nice boost again
