that sounds reasonable, very "green" technology smile.gif

so unless its implemented badly ( turbo doesn't kick in when its supposed to ) i don't see any problems with it... i shouldn't need 4ghz for browsing

That's not really a downside at all though. The switch to turbo mode is instantaneous and totally unnoticeable. By the time you even get to the main menu of a game (actually the second you launch the EXE for a game) your CPU is in turbo mode at your defined overclock.

If you're constantly running your CPU at its highest voltage and clock speed you're wasting away at its life.

There's a wide debate that having your CPU lowering/raising its clock speed and voltage are detrimental to its life, but I don't see why it would be if the voltage is well within its range.

Im 50/50 on the subject but what happens to a light bulb if you keep switching it on and off?

sure i see the pros of this and not many negatives if any!. Time will tell i guess.

5Ghz is so tempting but i want to save my money for Intel 6 or 8 cores.

Turning on and off != turning dimmer and brighter (correct analogy) You're not turning your CPU on and off, you're lowering/raising its voltage.

If you dim lights high and low repeatedly with those knobs nothing happens to the bulbs.

The reason its hitting a wall is 2 fold.
D1 chips are locked and there are bios settings that are available on the Intel boards that are not available on the other boards yet.

The D2 (retail) chips do not have the same limitations as the D1 chips and the other board makers are updating thier Bios as we speak.

Check out some of the benches with the Intel boards and D2 chips they have gotten up to 5.4 Ghz @ 1.576v on air.

I dont see Bulldozer catching up aside from highly threaded apps where the extra cores will give it an advantage.

You mean like a light curcuit with a variable resistor? ? not switching off completely. its the same as a volume knob up and down

Thats my question.. does the same thing happen on the cpu like at idle some parts are (switched off) so to speak or are they still running on low and when needed pumped up with extra power or are they (switched on)??

I cant see any performance diffrence weather or not the cpu is at a constant 4ghz base clock or on a turbo 4ghz clock. if its switched instantly it dont matter.
there's no need to use 5ghz and 160w to read emails.

I don't want guarantee it as I could be wrong, (again, there's a debate on whether or not changing voltage on the fly would cause any effects on a CPU's life) but I'm pretty sure all components of a CPU are always running regardless of turbo being enabled or disabled. Otherwise you'd see a more drastic difference in temperatures across your cores. You're not using any less of the CPU by opting to disable its turbo mode, you're simply restricting it from raising its clock any higher.

The switch is certainly instant, I assure you. I had my E8400 at 4.2GHz and now my Q6000 at 3.4GHz, both with Speedstep enabled which lowered/raised my clock and voltage depending on CPU load. The very instant you throw any load on the CPU, even launching Steam or Word, your CPU will go up to its higher clock. In 2500k/2600k's case, their turbo clocks are very appealing. My Q6600 is idled at 2260MHz I believe, and then shoots up to 3402MHz when I launch anything. I think even launching Chrome brings it up to maybe 2800MHz and then lowers it back down to 2260MHz. If I monitor the clock as I launch different applications I can see the frequency changing constantly, so by that we can safely say the switch is definitely instant.
