getting into home hosting. what's a better cpu option?

i'm looking at purchasing a dell power edge server to try some at home tinkering. ideally will be hosting videogame dedicated servers in the future. as i don't know much about server cpus. i wanted to ask if 2x E5-2680 will still make the cut, i also have the option to go with a newer E7-4870 Ten Core 2.4Ghz which i assume is much better
