Since I am already seriously planning to get an Athlon 64 system I asked how these systems were working for Poser users and got these very helpful replies. See attched link to Poser Forum. Also from Microsoft's website: "Compatibility-- Windows XP 64Bit Edition provides a rich platform to integrate 64bit technical applications and existing 32bit business applications using the Windows on Windows 64 (WOW64) x86 emulation layer, providing customers with the ability to move to 64-bit computing without having to sacrifice their existing investment in 32-bit software and Windows expertise." "Same Programming Model-- Developers with 32bit skills will be comfortable and quickly productive in the 64-bit Windows environment, finding it virtually identical to the development environment for 32bit Windows." "High Performance Platform for the Next Generation of Applications-- Windows XP 64-Bit Edition is a rich platform that enables the next generation of high-performance computing. 64-bit native applications can deliver more data per clock cycle, making them run faster and more efficiently."
