Despite the fact that Microsoft's 64-bit version of Windows is at least two to three months away, Gateway's 9310 series of high-end desktops lets you get on the 64-bit train early by offering it with Intel's new 64-bit-capable Pentium 4 600-series CPUs. We're tempted to question why a mainstream vendor such as Gateway would push a technology that will require users to make a complete software overhaul to take full advantage of its systems, but we can't for two reasons: First, Gateway places no price premium on the new CPUs, the configurations match up roughly with any 32-bit Pentium 4 500 series-based PC. Second, if our benchmark testing of the 9310XL is any indicator, the 600-series processors work just as well as 500-series CPUs in current 32-bit apps. If you've been interested in taking the next step in your computing hobby and you wonder what it might be like to upgrade an entire operating system, the 9310 series provides a convenient entry point. It gets the job done now, and it's primed to serve you well down the road.
