Are you familiar with emulation scene? At least I've been for many years and I'm a betatester for PCSX2 PS2 emulator for example and to me this is the perfect CPU benchmark since it produces graphics which is mostly taken care of by CPU, only the graphics plugin utilizes a bit of the graphics card but it's not enough to show any impact at all on the CPU performance, I mean I could downclock my 7900GTO to well below stock clocks and see 0 FPS decrease in most games, some are more gfx demanding than others though so it can vary a bit. It's either CPU or GPU that is the limiting factor, and depending on plugin and by enabling better quality settings the GPU load quickly rises so you can use it to bench GPU too if you like if using high enough quality.
I've compared my AMD Opteron 165 @ 2.8GHz and Intel setup both at stock vs stock, both at 2.8GHz and also 2.8GHz AMD vs 3.75GHz C2D and then at AMD @ 2.8GHz and heavily tweaked (as usual) with as tight timings as possible vs Intel setup at completely stock settings in bios so 2.66GHz with slacky timings etc. there was to my suprise even ~35% clock for clock advantage to Intel (I had expected maybe ~20% lol). Whit tweaked and maxed out settings on the Intel setup the difference rises to about ~40% clock for clock advantage as at C2D 3.75GHz vs AMD 2.8GHz there was a pretty consistent 72~75% advantage in most games to the Intel setup. The coders had AMD dual core setups at the time they've done huge improvements (such as adding dual core support) and there's nothing in the code that would make it more "Intel" optimized by any means, it's just shows the raw CPU performance with zero impact by GPU performance. :)
It's easy to make exact comparisions with PCSX2, I simply make a save state, load it at the different configs or setups and it loads the exact same spot and I've even matched the same polygon count to be as accurate as possible. I usually test different games in different spots to see how it behaves like and it's been a very consistent FPS advantage for the Intel setup. Same thing with overclocking, the FPS increase is pretty linear with the overclocked CPU amount. :D
I recommend these articles if you want to read more about it. They're old by now and and concerning a bit outdated PCSX2 version but yea it still explains quite good what I'm saying here.

Will of course do a comparision between this E6750 and E8400 Wolfdale later on, I'm guessing 10~15% clock for clock FPS boost for Wolfdale in this app, will be interesting to see what it actually will be like though.
