Dell Dual Core Intel庐 Pentium庐D 925, 2x2MB Cache, 3.0GHz, 800MHz FSB Vs. Dell Xeon?

Can someone tell me the performance comparison between these two servers? Both Dell.

1- Dual Core Intel庐 Pentium庐D 925, 2x2MB Cache, 3.0GHz, 800MHz FSB

2- Dual Core Intel庐 Xeon庐 3040, 2MB Cache, 1.86GHz, 1066MHz FSB

I will be using one of them as a web server hosting upto 50-60 domains.

thank you,
