nVIDIA and Core i7 Scaling Issue?

I know this is an old posting but the results seem to be replicated throughout the web at different sources. I was wondering if HardOCP would cover this rather odd behavior:

What you're seeing is that with an AMD Graphics card.. both i7 and Phenom II perform identically when a Graphics bottleneck is present. With an nVIDIA Graphics card.. the i7 seems to bottleneck before the Phenom II does on the graphics end.

It seems to be an nVIDIA driver issue (as lower resolutions with nVIDIA Graphics hardware or using AMD Graphics hardware showcases the correct expected behavior).

This is an oddity and I was wondering if HardOCP would cover it in order to push nVIDIA to fix this issue. Most nVIDIA users are paring their cards with a Core i7 rig and most are not aware that they're not getting the performance they should be.

Thoughts?

It has been seen before, with the GTX280:

Gotta read the link before posting.

Yeah... it appears it's still occurring. You should be getting higher frames than you are right now Atech.

It probably has something to do with nVIDIAs Multi-threaded implementation tweaks in their drivers.

Maybe they don't like HT?
