<br>More like too little... Dude's computer crashes and has a glitchy power behavior after he tries to use the opengl subsystem... I'm guessing he might be able to get away with bumping up the voltage to his ram (cheap ram) and chipset (cheap mobo), or his powersupply isn't up to the task.<br>
<br>I've just build the latest generation of PC's for my family (and the wife's) and all the power supplies I kept squirreled away did me no good. We've migrated to the dual core / > 2gb ram range and during burn-ins I'd see the same sort of behavior.<br>

I've done some similar measurements with friends using the same sort<br>
of reader. My results are online, if anyone is interested:<br>

My tests are all on smaller machines, but i agree with Brian's<br>
assessment that power consumption should in general be going down, not<br>
up, especially if measured against computational features (CPU<br>
cycles/sec, MB of active RAM, throughput to disks, etc).<br>
<br>
If your machines are getting more power hungry over time, and you're<br>
not a serious number-crunching scientist or an insanely-committed<br>
gamer, you might be spending too much money on hardware (not to<br>
mention on electricity).<br>
<br>
even for rack-mounted servers, i'm finding that the significantly<br>
more-powerful modern machines pull about the same amount of juice as<br>
the older, feebler ones. With virtualization, i can support 3 or 4<br>
old-machine-equivalents using the same amount of power on newer<br>
hardware.<br>
