There are quad core i5's in the garage, one is running the g0704 and they are too slow too, and think they are i686's to boot. 17,000+ bogomips.

Maybe its time to build a new machine here. But this one is like an old friend. Hate to put it out to pasture. I've looked around, and by the time I put a new board and cpu with a dozen cores and enough memory to adequately run some of this stuff, (and still be fighting with a video card that runs at 5% speed on linux. I'll have 2Gs in it. All to do gfx like the amiga 4000-060 in the basement, which in its day could roll and rotate to see the back side of a full color ntsc image in real time just by grabbing a corner of it and dragging the mouse. And it did it with 16 megs of dram and a dual core 68060 50 MHz processor. What the hell has happened? We are spinning a lot of wheels doing nothing is whats going on.

Worked well, till it caught fire because a 75 cent fan failed and apple wouldn't touch it because it wasn't running apple SW. $14G's we put it that A/B roll gfx system and it was all up in smoke in 5 months. We got screwed, and I don't think the tv station has bought an apple product since. We had bought some pizzabox video servers at about the same time, and their fans were junk too. We have several $ I think) each capable of recording and playing 6 channels of 20mhz digital video now, rigged up as auto-failover so if one fails, the next is online, and in synch, in a few milliseconds, and Jim Hines built them all. Running centos. And we haven't seen a BSOD on the air since we terminated the 'weather channel'. They built their own building in our back yard and filled it with winderz XP machines, but they wouldn't replace it when it turned into a crasher a dozen times a day. The owner, who was a personal friend of mine, died about 2 years back and his daughter sold it, to Grey. For an obscene amount of money. Grey's people toured the place and dictated that the linux machines had to go. Funny thing, nearly 2 years later, the 2 linux servers there then are still there and 2 more have been added once they looked at how dependable they were vs the cost of all the winderz machines it would take to replace them. Computing has come a long ways, but despite huge improvements in the hardware, you can measure the progress with a shirt pocket ruler.
