If your are currently running a 32 bit OS you can determine if your system can handle 64 bit Window 7 by running the Windows 7 Upgrade Advisor. I all depends on your processor’s capabilities. Just switching to a 64 bit OS can be a significant improvement in performance. It’s worth a shot if you can’t get new hardware right away.
A word of caution. Object enablers may not be available in 64bit versions. ODBC drivers may not be available in 64bit.
