server needed

Hello Everyone

i’m new here and want to ask couple things related to dedicated server. 

Currently i’m using 
– Intel Xeon x3330 (Quad-core, 4×2.66GHz)(64Bit 6MB L2 Cache)
– 8 GB ECC RAM
– HDD 2x500GB SATA II RAID0/1
– cPanel
– Location USA
Is there something else similar or better/cheaper?

Thanks for any advice.
