To answer your last question, not only do they need to be the same speed, but also the same stepping code or else you'll have lockups and not enjoy your dualie experience, i am still debating internally about going to dual system, but since my home system is mainly for research gaming there really isn't a need to go to duals, unless someoe can prove that dual processor and geforce2 really do improve the gaming experience, otherwise, there is no use. Anyone know where I can find a good low cost p2 xeon mainboard. i see the processors all the time on ebay and may just pick up a set for myself but the mainboard is what holds me back
