So I'm going back and forth on the system I want to build. I always wanted a Ppro system and if I went that rout I would go with a Pii over drive. But I also always wanted to max out of K6-iii+ system too.
I know the sk8 system would lack SD ram and agp but that aside how to the two stack up ?

Thanks!

PII Overdrive is 'only' 300/333MHz.

K6-III+ starts at 400 MHz for the embedded version. Yesterday I ran Speedsys with this processor in particular, overclocked a bit.

A K6-III+ @ 550 should have :

a significant advantage on integer code for older games & general usage
a slight advantage in FPU performance for 3d games
a Super 7 platform that supports 100Mhz bus, SDRAM, AGP Graphics & UDMA storage

But a K6 @ 300 would be:

slightly slower at integer code
weaker FPU performance
on any of a wide variety of chipsets, 430FX through Super 7 so the platform can vary greatly, while the socket 8 boards were almost all in a pretty narrow range that had a 66Mhz bus, EDO RAM, PCI graphics & MWDMA storage

I’d guess the K6-3 + would be decently faster.

On YouTube, there’s a comparison of a Tilamook overclocked to 420mhz compared to a standard K6-2 at 420mhz. Generally the K6-2 wins by about 15%, although most of those wins are synthetic tests. The actual game performance seems fairly close.
