Some of those charts suggest the exact opposite. Those figures make an upgrade for me look utterly worthless...?
Battlefield 3, medium settings, 1920x1200:-Q6600 = 72fps
I7 = 78fps
Battlefield 3, ultra settings, 1920x1200:-Q6600 = 45fps
I7 = 48fps
So hundreds of pounds of expense for a under 10% improvement?
That's VERY worrying!
The only significant improvement I could find was:-Metro Last, highest settings, 1920x1200:-
Q6600 = 33
I7 = 51
That doesn't seem to back up starmanwarz's suggestion BF3 doubled in speed!?
Figures seem to be based on a GTX570 so I'm calling GPU bottleneck.
I had a single 560Ti 2GB and it was just fine with a nicely OC'd Q6600 however when I added a second GPU it just didn't scale. A 560TI and 570 are quite similar in performance.
I'd speculate that a lot of games in the era had balance performance with a GTX5XX card and Core 2 Quad but my benchmarks were is a different class with a clocked 2500k and SLI 560's
