Processador Intel Xeon E3-1240 (LGA1155 - 3,3GHz) - BX80623E31240SR00K - Box
Processador Intel Core i5-2500K (LGA1155 - 3,3GHz) - BX80623I52500KSR008 - Box
I am not very familiar with Xeon procs nor iX classes but from what I readed from both, they are both quad core with 3,3GHz the main differences are L3 cache 1 is 6mb other is 8mb and the TDP being one 80W and the other 95W and the fact the iX have the intel graphs integrated.
Price difference from 1 to another is 50USD where I live.
If it helps the motherboard I was thinking of buying for this is a Gigabyte GA-Z68XP-UD4
Would like to hear some advices from experienced users.
