AMD Servers

Wanted info on AMD Servers. We are in the process of buying AMD servers for Our Lotus Domino, Oracle 9i App and Citrix Apps. We have boiled down to 2 choices IBM X3655 and the HP DL 385G2 both of which are AMD Model 2216 at 2.4Ghz. Wanted to know if AMD is good or shld i move to intel only. Has anyone used any of the above 2 server models . Would appreciate ur feedback on the same .

Thanks in advance
