Probably enough if you have "normal" source files.IMO, if you have a
need to check in/out huge binaries, probably not.

I don't know how helpful my info will be (OK, I *do* know - not very)
but our subversion repos are hosted by an IBM quad proc box (power5
architecture) with 16 gb of RAM, two fiber channel adapters, and the
repos themselves are hosted on a SAN filesystem with about 450 GB free
on our svn volume. I think there are 4 gigabit ethernet nics in it too.
Way, way overkill for our SVN needs. :)
The same box will soon be hosting some largish development databases for
our QA dept.
I can't post the cpuinfo, free etc info because we're on AIX here. :/

 8 - CPUs currently |
| 8 - CPUs configured
| 1498 - MHz CPU clock rate
| PowerPC_POWER5 - Processor
| 64 bit - Hardware
| 64 bit - Kernel
| Dynamic - Logical Partition
| ML05 - AIX Kernel Version

I know it shows 8 cpus, but it's really 4 dual core cpus.

I'd go ahead and get the new server your boss wants, not so much for the
speed increase but for the reliability of a newer server class machine.
I'd also recommend a raid disk configuration, both for speed and
