sorry to dissapoint you but since the question was about a computer, here's this:
if you ever bought an iPod nano for a computer, then let me challenge you by going to f1technical, me with me pc, you with your iPod
Anyway, a computer... a blade server could be it
or actually the new IBM blue Gene/L computer which is the current MIPS record holder. It's supplied with 65.536 processors and performs 280,6 x 10^12 floating point calculations /s. This was set few weeks ago while the previous record was not even half of that number (set by the same computer half a year ago when it was only partially completed)
Imagine what would happen when some team suddenly realised a 100% gain in performance on track
