Sounds like Munir's answer made this a moot point, but I need to set this
straight.  The 835 has a 128kB unified I/D cache, two-way set associative.
The 730 has 128kB I-cache and 256kB D-cache, direct-mapped.  The whole
point of staying with off-chip caches was to make them large enough to
handle real applications, server or otherwise.  You can argue expandability,
but the cache on a 730 will outperform that on the 835 in virtually all
cases.
