Thanks mate, To be honest I have't considered Xeon E3-1231 V3 because I made a list of components for my computer build I have send it to my friend and he told me not change anything exept of the CPU, he told me to change I5 to i7 i7-4790K CPU I was't rally sure because that is a quad core when I was thinking about 8 cores but I think that quad core will still performe just fine
