The increase is substantial. The increase is noticeable even among 2/4/6/8 cores of lately.
What are you trying to say here? Upgrade your video card and see an increase in performance, downgrade your CPU on an old dual core system and you will see a decrease, then upgrade again to see an increase?
Upgrading your graphics card produces significant performance increases when you are not
CPU bottlenecked. Downgrading said CPU to a point where you are bottlenecked will indeed
make you bottlenecked, obviously. This is not a new discovery.
Your assessment of the obvious, however, doesn't apply to the context in which he was speaking. Most people running even an old quad-core Nehalem will be able to run high-end multi-GPU setups without being bottlenecked by their processor. There are some architectural improvements from Nehalem to Ivy that improve GPU performance, but that's not to be confused with being "CPU limited." Ivy will help squeeze a few more frames out of one card over Nehalem, the same way it'll help squeeze a few more frames out of three.
