While its true
That if you want absolute top performance you go Intel, frankly that 30% gain comes at an 80% to as high as 150% markup when all the parts are added up, such as boards. and don't forget to get ALL the features on an Intel CPU you often have to buy the most expensive chips as Intel cripples the lower SKUs, whereas ALL AMD chips support the features, from the lowest C50 netbook chips up to the biggest Opteron.
personally I'd say where AMD has the big winner (and where the CEO seems to agree as he has slowed down the desktop output to crank up the mobile) is in the Brazos line with chips like Zacate and Ontario. I've been selling netbooks and laptops based on Zacate as fast as i can get them through the door and the customers love the things and with good reason. great performance and 6 hours of HD video on a single charge in a machine that weighs less than 4 pounds for the lappy and just 3 pounds for the netbook. I was impressed enough i put my money where my mouth was and sold my MSI wind for a Zacate EEE and i see why they love it, it is a wonderful chip.
The only real problem AMD has ATM IMHO is they can't seem to keep up with the demands for the mobile chips! you go to any PC retail site like tigerdirect or Newegg and you'll see the OEMs are using the Brazos chips in EVERYTHING, from netbooks and laptops to all in ones and HTPCs, the things are everywhere. and on the server front I know a few admins and they've told me they went AMD because the bang for the buck was nicer. with AMD they were able to load their servers with more RAM and faster SSDs at the same price compared to Intel and when you are running heavily threaded loads the AMDs do the job well enough for the price.
So i say stick with AMD, but maybe hang back on Bulldozer. it looks like another Phenom I where they'll need a rev to get the kinks worked out. stick with Deneb and Thuban on the desktop and go Brazos of Phenom II Quad on the laptop and by the time those get long in the tooth the chip after Piledriver, where they will have switched to the vector based GPU (which will seriously kick up FP performance) will be out and the prices will be nicer. On the server magny cours is a great bargain and for most loads works quite well at a very cheap price.
