Processor preference?

I'd prefer Intel performance wise, but AMD is just so much cheaper. Look at these two:

Similar, but not identical. The Intel is slightly better, but you could get two AMD cores for the price of the Intel one. Granted, AMD cores aren't optimized for the stronger (and possibly cheaper) NVidia graphics cards, but I prefer AMD nontheless.

Those two are completely different. Apples and oranges.
Plus, the difference in performance is massive.
About AMD's recent approach; more cores != more performance. They're still the crappy K10.5 arch that barely competes with the Core 2 series from Intel. Pretty sad, really. Bulldozer better be good.
Also, "AMD cores aren't optimized for the stronger (and possibly cheaper) Nvidia graphics cards" statement is completely false. They're both equally optimized, it's just the Intel is simply more powerful.
