Xeon Processor Question

[Muck]

Been out of the hardware game awhile and was looking for some advice.

I've currently got some matching web servers with dual 2.8GHz, 800FSB Xeon's (single core) and parallel 10K SCSI drives (no RAID). They see a good bit of traffic and handle it pretty well. Databases reside on other beefier servers.

The servers I'm looking to buy would have Xeon 5110's and 15K SAS drives (no RAID). What kind of performance difference am I looking at if I opted for single procs rather than dual compared to my existing setup?

I'm trying to squeeze what funds I can into upgrading other portions of my project. Is this an area I can do that?

Thanks

The Xeon 5110 servers will require much less power, run cooler and most likely be faster than what you have now. You are not giving up anything by going from dual single cores to single dual cores. In fact, there is less overhead with a single dual core (not to mention you'll also get all the benefits of the Core micro-architecture, mentioned above). I say pull the trigger.
