The Mac Pro 3,1 is arguably the greatest Mac Pro that Apple made when it came to price. Such a solid-ass machine. Bought new, lasted me 8 years before I decided to go to a 5,1.
And a 5,1 was a big difference. Do not buy a 3,1 now. They're really not worth much anymore. I got $280 for mine about a month ago and I was lucky to get that, and included original box, etc. I did a BTO and got a 8800GT right off the bat (and the wireless card, which wasn't standard), but then I upgraded to a 4870 which was a better card. Sold that with the Mac Pro.
Don't get unless you don't care about power and want a secondary "Aux" computer.
