Kindly suggest which of the following server will perform better.

i7 2600 + 16GB RAM + 2x Consumer SATA H/D in Soft Raid 1
i7 920 + 24GB RAM + 2x Consumer SATA H/D in Soft Raid 1
Xeon E3-1245 + 16GB RAM + 2x Enterprise SATA H/D in Soft Raid 1

In start I will be running all the 3 servers (web/db/asterisk) on single machine, but later I will move the db and web to separate servers. So please suggest which machine will perform better in single use and which will perform for running only dialer.

according to CPU Benchmarks (http://www.cpubenchmark.net/high_end_cpus.html)
i7-2600 score is 8949
i7-920 score is 5567
Xeon E3-1245 score is 8697

Telling us how many cores are in each CPU and what the CPU cache is would help.

i7-2600
Cores: 4

Dialer = machine 1
web server = machine 2
DB = machine 3
