Even though they aren't really a real option in PCs any more that'd be a big deal for the XB1 and PS4.
You couldn't be more wrong. Not everyone can afford to spend the $$$ Intel asks for their processors. Plus, when it comes to price/performance ratio AMD pretty much wins in most cases. Of course, if you have the $$$ to spend go buy whatever.
Over the past 20 years I have never seen an AMD machine work in an office environment without mysterious crashes and other mayhem. Fine for a few hours of gaming use per day but not if you need to depend on it. People around me tried to buy AMD systems and even at some point a co-worker ordered a whole bunch of AMD based machines but they where replaced in 3 months.
The bottom line is: Better buy a slower Intel CPU in a properly designed PC and get work done instead of losing your work all the time.
I think it really had to do with the chipset and peripherals. Intel machines were usually "full Intel", including stuff like chipset, graphics, audio, lan etc. Basically just the Intel reference board. AMD never did that, manufacturers had to select their own components. Boards with Via chipsets and peripherals were good, but there were some very dodgy chipsets and peripherals that manufacturers could use (SiS 730... ALS4000 audio... ).
Never had issues with my AMD machines, but they did have motherboards with reasonable peripherals on them. They were also just as expensive as an equal Intel board.
Somewhat ironically maybe, the only system I had issues with was an Intel P35 system, that chipset had some serious cold boot issues.
