i meant you should go for a higher one than only 600w lol
and i can confirm from personal experiences, that an decent i5 could easily get bottlenecked with one of the newer graphics cards, such as my 980 strix i have right now
of course, i5's are still running strong as of right now, but from what i'm building, i'm not aiming for "right now"
if i actually want to get anywhere, i'm going to have to max it out, and that's the reason to why i, myself, am getting an i7, because my i5 already can't keep up with editing very well, and is soon enough going to have trouble running the current games
