I'm trying to end this thread...
A few comments for NOS440.
You complained about the lifespan of the KX133 chipset. Then in the next post, you exhalted the P4. Keep in mind that the initial chipset on the P4 is expected to last about about 8 months. Quite a bit shorter than either the KX133 OR the AMD750 lasted. Keep that in mind...
Next, if you say that you care about nothing but performance- regardless of how difficult it is to obtain, I encourage you to go out and buy a 1.1Ghz TBird. Since you complain about having to use a pencil to overclock, let me point something out. It is quite accepted that the KT133 can run 110-115 MHz FSB virtually all the time. With this 115MHz FSB, you can overclock this chip to 1265MHz. You will probably get closer to 1.2Ghz max, but that is plenty to beat out even a 1.13Ghz PIII. Despite the fact that you don' care about cost, that this 1.1Ghz chip would cost you about the same as a PIII-800 which is doubtful to reach 1Ghz, let alone 1.265Ghz.
I encourage you to look at Anand's reviews of the TBird vs the CuMine.
[*]"To start things off, the Athlon boasts a 14% performance improvement at 1.2GHz over 1GHz under SYSMark 2000. "
[*]"1.2GHz Athlon still manages to pull away to offer the highest x86 gaming performance available. "
[*]"1.2GHz offering manages to pull away from everything else with ease. "
[*]"1.2GHz Athlon continues to command a healthy lead"
[*]"The 1.2GHz Athlon continues to provide a 10% lead over the 1GHz Athlon as well as the 1GHz Pentium III"
[*]"slap in the face to Intel"
Now I'm going to list all the test results just 1Ghz TBird vs 1GHz PIII- I will list which wins and by how much. Maybe then I'll add them up at the end

Note: I left out the tests that weren't CPU limited. They're sorted by how much each chip won.
SPECvp- DX-6: Athlon +31.6%
SPECvp- Awadvs: Athlon +15%
SPECvp- MedMCAD: Athlon +11.3%
SPECvp- ProCDRS: Athlon +7.8%
Expendable: Athlon +2%
CC Winstone 2000: Athlon +1.7%
High End Winstone: Athlon +1.4%
UT 1024x768x32: tie
SysMark 2000 Win98se: PIII +0.5%
UT 640x480x16: PIII +1.3%
Q3A 640x480x16: PIII +2.7%
SPECvp- DRV07: PIII +6.7%
Note: When the PIII wins it never wins by more than 7% and averages 2.8%. Athlon, however, prevails 64% of the tests and generally beats the PIII by 10.1%.
In some reviews, the PIII beats the athlon more frequently, but almost never by more than 5% where the Athlon beats the PIII occasionally by 30%.
Additional resources:
See Tom's Hardware MPEG encoding- TBird is best.
Sharkey's- TBird 1ghz and PIII run neck and neck
HardOCP: Athlon wins by a large margin.
Is that enough to convince you?
Ok- now step back and realize that I've been talking about a 1Ghz TBird- selling for under $300 and 200MHz slower than the top-of-the-line.
I won't argue that the PIII is worthless but trying to convince someone that the PIII is worth twice as much money is flat lying.
