I have noticed that a lot of you are running QS with 133MHz System bus. What do you picture about a 'sawtooth' bus speed 100? Would 1.2GHz give most for the money or 1.4 (as they have L3 support),or the 1.7? The system bus is a bottle neck.

Would I get a much better speed if improvement by getting rid of my sawtooth and getting a DA or QS with PC133 memory and bus speed 133MHz to put the cpu upgrade in?

Since the bus speed is a bottleneck, you want to minimize RAM access as much as possible. Thus the L3 cache will be a nice benefit to your system performance.

Would I experience a speed boost with a 133MHz system bus compared to my 100MHz?

Not really.

If you have a Sawtooth, like me, get an upgrade with a large L3 cache to offset the slow bus speed. Trading it in to get a system with a 133MHz bus won't help at all. jamil5454 is right on the money.

From the real-world benches I've seen, the L3 provides somewhere between a 5% to a 30% boost in speed.

So, A G4 7447A at 1.7 GHz might be equivalent to something like a G4 7457 with L3 at somewhere between 1.3 GHz to 1.6 GHz.

Thus, a 1.4 GHz with L3 or a 1.7 GHz without would both serve you fine. The 1.7 is killer on Xbench though.
