There's a big reason why Intel isn't officially at 3.8 GHz right now. They left AMD in their wake last summer and haven't been pressed to look backward until now.
I'm guessing that it's pretty difficult to OC a G5, although the cases are pretty cooling-oriented. In order to speed up the chip, you'd *probably* have to speed up the bus or change the multiplier- I'm not sure that either of those things is easy to do.
Still, 3.2 -> 3.8 is less than a 20% improvement, and it's *only* a *single* *processor*. Most things that are compute intensive enough to be totally CPU bound can probably be parallelized.
I'd take a dual 2Ghz G5 over one of these any day
I'd take a 4-way 3Ghz G5 over one of *those* any day

Some, but not most. Many interesting things like cloth simulations or maximum entropy image filtering techniques need to be done globally and sequentially, which makes them incredibly difficult to parallelize, as each tiny step depends on the last tiny step's result.

That's because the CS guys have gotta start using their brains and hence make some parallel implementations of cloth simulating algorithms. . .
Anyway, I haven't actually found a way to buy anything off this site. If there is a way, they don't make it easy.
No offense to those that posted in this thread, but I'm midly suprised that nobody was familiar with this particular form of overclocking.
Basically the problem with running processors faster is that they generate more heat, and you eventually reach a point where the heat generation is critical (i.e. aircooling doesn't do enough to prevent the chip from nuking itself).
Refrigerated cases are the ultimate in modding your PC for the purpose of squeezing out every last possible MHz. The technology literally keeps the temperature of the CPUs well below freezing in order to push them to their absolute limits.
as long as you an take the heat away, the chips will run VERY fast. I remember seeing benchmarks for a 4Ghz P4 when the fist came out with the northwood model name....
... Its true, they were right next to the pictures of the chip with a pot of liquid nitrogen sitting on it!

On the other hand, they are very expensive systems - I guess they complement the insanely huge LCDs that they sell.
Copying Apple? At least they have some taste...

Of course there's no 3.8 yet.

Yeah. You can do this yourself and save some money!
My 3.2 is only stable up to about 3.7, but I don't have any special cooling so I don't run it like that.

THERE IS NO 3.8Ghz P4, YET!

Hell overclocking pc freaks are having trouble getting it past 3.6 Ghz and that is with very exotic cooling.
The next core intel pumps out will hit 3.8 but that is still yet to be released.

edit: found it! - It was a 2.8 P4
Some people have too much money and not enough sense!
more edit: he he... -192 degrees heat sink!!!

Seriously, I don't think that the system will actually last very long...chips, liquid N or no liquid N, aren't designed to be that hot.
