As technical applications have matured, the bounds of 32-bit computing have become a daily reality - memory swapping for complex 3D models, glacial rendering times, elaborate workarounds - not merely a theoretical limit. Meanwhile, UNIX shops coveting the mounting advantages of mainstream workstations count their own woes, from high initial cost to lagging graphics performance. The transition to a standards-based 64-bit solution was deadlocked in an either/or world... until IBM turned the tide. Consider the IntelliStation Z Pro with Intel Xeon processor, featuring Intel Extended Memory 64 Technology (EM64T). Set a faster pace with familiar 32-bit software while growing into key 64-bit applications, optimizing your workflow and maximizing ROI. With IBM, it's all about making the choice easy: 32- and 64-bits, Microsoft Windows and Red Hat Linux, 2D and 3D graphics tuned to your applications - whatever's best for you.
