With the 10.5.6 in sight,I am contemplating moving to leopard. My 06 MP is loaded with a Raid10 (4x500gb) and wondering is it worthwile or even possible to instal leopard to that setup? It is my production machine (fcp and CS3) and on the top of usual hesitations of upgrading the os,the main problem is if the update is possible at all? Does the update go well and what kind of problems have people had after/during? I only found couple of obscure remarks where people were talking about constant kernel panics and stuff. One reason for the update would be graphics card (apprently 8800 and 3870 etc dont work with tiger?)... Anyone?
