BTX would've "caught on" by now if it were ever to catch on.
But look who hyped and pushed BTX? INTEL!!
Except for overtime-shift schedules to meet world-wide demand for their run-of-the-mill processors, who or what would recommend Intel for anything extraordinary this year?
They fell on their face with the Smithfield in THG's marathon hardware playoff with AMD.
Their motherboards are designed to keep you from exploiting the safe limits of their mid-range CPU's so they can sell their top-flight offerings for top prices. Their processors are designed with the same thing in mind.
They were under investigation by FTC during 1999 for "price-discrimination" practices through minor disabling of their Pentium-2 333 Mhz processor from the same production runs as all the other P-2's, so they could market the 333 for a higher price and the 300 or 266 for a lower price. To the uninitiated, this means that they capture more profit from product sales than if they simply produced the 333 and sold it to everyone for the same price.
If they haven't turned around in six more months, get out the shovel, call the coroner. INtel may be as big as Big-Blue, but their spirit is day-ud. It's day-ud.
