Here are some benches to compare the "Game Acceleration" options in the new "025" BETA BIOS (Version 14??). These replaced the "performance mode" options in previous BIOS versions.
I didn't have a bunch of time to spend on this, but you should get some idea of the performance difference between the modes. Also due to lack of time, I did not run stability tests. I will say there was no sign of instability during any of the benchmarks.

TEST SYSTEM
Abit IC7 - BIOS version "025" Beta
P4 2.6C SL6WH Pack 05/02/03
No overclock
Corsair XMS3200C2 (2x 512) mb
Alpha 8942 - Panaflo M1A
Radeon 9700P No overclock
Antec True330 - 330 watt PS
Win XP Pro SP1a
DX 9.0a
TEST SPECS
ABIT IC7 i875P = 1.525 Vcore | 1.55 VAGP | 2.8 Vdimm | PCI/AGP 66/33 | 1:1 ratio | DC DDR 400 | cas 2-2-2-5

The settings seem a bit more aggressive than the 13 BIOS "performance mode". With mu normal 257 FSB overclock an 5:4 ratio, I could boot and run with "turbo" with the 13 BIOS. It was almost stable, but would error in Prime95 after an Hr or two. With the 025 BIOS, I can not complete a POST with turbo enabled even with relaxed mem timings.
