Well, they look to be p4 Xeon's. So it's not really a bad price ... but like others have said, unless you really need the extra horsepower (ie: have programs that are going to make use of it), then you'd be better off, configuring a 3ghz single p4, for less money, and more usable horsepower.
If the programs you're going to use don't have multithreading support, they'll only use one processor, while the other will essentially sit idle. So you'd be running at 2.4ghz, not the equivalent of 4.8ghz, if that's what you were hoping on accomplishing.
