I am building a server which will host various websites on IIS, and also have multiple MSSQL databases. I'm currently trying to decide between 2 x AMD Opteron 6128's (8 cores each) and 2 x Xeon E5620's (4 cores each + Hyperthreading).
What do you think would be the better choice, and why? I can't find too many benchmarks of those two in a web application scenario like mine. Thanks for your help!
