Using (or not using) MP processors is probably more important than the case you use to deploy the PUs in. In Canada, prices for Athlon XP processors hovers around $350 CAD. Using MPs pushes this to ~ $500 CAD. For a basic node, this is a significant cost increase. Generally, SMP should help performance compared w/ 2 single CPUs (by Amdahl's rule) as average communcation speed is much higher. All in all, though, it depends on the application. For we who don't run diskless, SMP saves another $140 CAD (can't stand POS - Fujitsu - drives). If XPs can be used safely with modern Athlon mobos, I don't think there's any question that SMP is worth it (if you don't care about waranty). Things get dicier if MPs are a necessity. Does anyone have a success story about XPs and 760 MPX motherboards?
