Yes, AMD delivers good value. December2010 I bought a new workstation equipped with an AMD PhenomII 1075T, 16GB ECC RAM, an high end ASUS board, and 5 1T disks (boot + 4 as RAID 5 fake raid), an passively cooled ASUS AMD 5570 video card and an silent CPU cooler all in a Fractal Design Define case. I paid less than €1000 for it. Even today I would pay more to get an Intel based system with comparable specs. Choosing Intel I have to use Xeon processors to get official ECC RAM support.
But I am not AMD only, a few month ago a chosed an Intel Core i3-2367M based laptop for my wife.
I am a huge fan of Intel and employ two Core-i7 PC systems in my home. But game manufacturers are going to this 8-core AMD CPU for one reason only: cost. Don't forget that the price of a new game consoles is usually the price of a mid-to-high end PC graphics card. For me, game consoles always set the bar a little higher for PCs
This is the first time I've ever seen a computer system using GDDR technology as main memory which makes me wonder if AMD has also built a custom memory controller. Also, take a look at those CAV specs for the optical drive. Rumor has it that the XBOX-720 (a.k.a. Durango) will also shift to x86.
