Farside; Poser runs swimmingly on an Athlon 64. Can't comment on the Intel chippie, as it isn't available yet, isn't true 64 bit, and I haven't used chipzilla's products since the 386-SX. However, the Athlon 64 code is nothing but good old X86-32 code with 64 bit extensions bolted on...the way the bolted the 16 and 32 bit extensions onto the original 8 bit X86 code. So no problems that I've encountered. Fish; Those Lian-Li tower cases are wonderful, aren't they? 2 sound cards? You don't run Adobe Audition perchance, do you?
