That is assuming CPU is the defining factor in the speed of your computer. For vast majority of users, this is just plain false -- a 60$ Athlon II dual core with a 200$ SSD massively outperforms a 950$ i7 975 that is paired with a traditional HD in nearly all of the use cases a normal desktop user encounters -- And if you are into gaming, that same 60$ processor paired with a 300$ HD5870 high-end graphics card easily outperforms the same i7 paired with HD5850, the next-best model that costs only 50$ less.
Good point, but not always true. It's a myth that game performance is universally GPU-bound. Most notably, most MMORPG's, many RTS's and pretty much anything made with the Source engine are more dependent on CPU performance.
