My old server is using the results as the given below and i will transfer it to my new server but i have 2 option infront of me

Firstly my old servers properties :
Q9550 CPU and 12 Gb ram

New server 1 :

2 * Dual-Core Intel Xeon 2.8 GHz Processor with 4 MB L2 cache.
and 16 GB ram

New server 2 :

2 * E5420 Cpu and 24 Gb ram

but i do not want to let the second server use for this system.
The most busy time scores as given below.. Do you think first server should work with this system.

You will cut your processor cache memory by 1/3 using server1
Note that you may face big difference if you migrate to server 1, because you will reduce from 12mb of cache to 4m.
It's like comparing a regular intel processor with a celeron which is nothing but a regular intel but with reduced cache version.
Keep in mind that processor cache is the fastest memory ever, and the more expensive memory ever as well.

Cheers 3XLcom:
At normal times, the server 1 will easily handle your current load.
You must concern only about the peak times.
I'm always here if you need
