Which is a better set-up for gaming and youtubing out of the two builds below?

i plan to buy during christmas sales and get it built in a week or so

so i recenatlly pushed my budget to £500 and i want to see what is the better set up for the following

ill be using this as my first PC for games like

fallout 4
total war
minecraft
upcoming games 2015 -2016 and onwards
editing on sony vegas and youtubing
day Z exile and other mmo
and top tens

high settting would be nice like 1080-720 with good FPS 50fps +

ive asked other places and many people and forms have said I5, but many yotubers have made reviews of xeon saying its the as the same as a i7 so im unsure what to pick as my set up
