Well, the 8K7A/MP setup will be a second rig for me, so I could bench it against my current rig (1.2ghz@1.4ghz, KK266-R, 165FSB), and I could switch out the CPU's and try them both on each board. If my suspicions are correct, the performance difference between the cores would be less with SDRAM because the hardware prefetch won't be as benificial as it is with DDR. I will also be able to see if and how it works on a KT133A based board. I will keep you posted...
