Thanks, that situation is a bit different, but very helpful.

Here we would have:

MDD: Single 1.8 GHz 7447a 167 Bus

QS '02: Dual 1.8 GHz 7448 133 Bus

Your (johnklos) results show that for data intensive things, the QS would beat out the MDD. This would be even furthered by the dual cpus. Would the smaller benchmarks do any better with the dual cpus?

Would the NewerTech upgrade have 1MB cache shared by both CPUs, 1 MB for independent for each, or 2MB that they can both access? Obviously, no L3 cache.

*Quasi-relevant: http://forums.macnn.com/65/mac-desktops/356348/dual-7447a-or-single-7448-a/

Summary: Same Bus, Slower Dual 7447a faster for most things than Faster Single 7448.

Notes:

Leopard runs a lot better on dual cpus. The 7448 is a good bit cooler and draws less power.
