Which configuration would you choose for your dedicated hosting setup?

Forget price in this setup. I am trying to figure out the best server for a web server and the best for a database server based on the options below.
I'm not sure how important those faster SAS drives on my DB server are compared to SATA drives. Is RAM more important for my DB or my web server if I can make an upgrade for just one?

My choices:

option 1:

Web server:
Harpertown 5420 2.5GHz (Dual Processor, QuadCore) with 12mb L2 cache

DB server:
Clovertown 5310 1.6GHz (DUAL processor, QuadCore) with 8mb L2 cache
2x73GB SAS (RAID1)
4GB RAM


option 2

Web server:
Harpertown 5420 2.5GHz (Dual Processor, QuadCore) with 12mb L2 cache

DB server: Harpertown 5420 2.5GHz (Dual Processor, QuadCore) with 12mb L2 cache
2x250GB SATA2 (RAID1)
2GB RAM


option 3:

Web server:
Harpertown 5420 2.5GHz (Dual Processor, QuadCore) with 12mb L2 cache

DB server: Harpertown 5405 2.0GHz (Dual Processor, QuadCore) with 12mb L2 cache
2x73GB SAS (RAID1)
4GB RAM

 

i would say option 2 is the best

 

For database server take alot of ram and less processor power.

 

No, actually Database servers use up more CPU than RAM because they process the queries.
Option 2 is the best because it has loads of CPU power, enough RAM and SATA hard drives have been proven faster in benchmark tests but SAS have been proven more reliable.
