Work Rant

We have a large project we are working on in Revit.  A while ago, we did a test job and it was decided we needed to upgrade our systems to work on this large project.  We got them less than a year ago.
What are they?  HP Z600s.  After our tech asked me to find him some numbers from BOXX and the like and building our own systems, he went with the lowest Z600 he could find.  It's a Quad Core Xeon.  Xeon's are great for people doing multiprocessor, or large amounts of ram.  Our system has 3GB.  Seriously, that's it.  It's 2.0 Ghz. It doesn't have hyper-threading, not that the version of Revit we are running uses it.  Think of the future at least!  We also have Windows XP installed...
Revit runs horribly slow.  Takes too long to open, to save, close, move something, circuit something, etc.
What are our upgrade options?  More Ram.  6GB or 12GB at current prices is $170/$340.  But what good is ram without a 64 bit OS.  We can't upgrade to a 64 bit OS because we'd loose everything.  We can't have downtime like that.
What am I saying?  Spend the extra $$$ in the beginning to get something somewhat decent.  I am crippled by OS, why stay with XP?  Windows 7 was out when these were purchased.  At 64-bit Windows 7, we could have stayed on it till ram prices dropped to their current prices.  Or, for whatever price they paid for these systems, I could have made something superior cheaper.  You don't need tech support, that's what in-house people are for.  Ugh.  2 Ghz... Dream machines. :rolleyes:
