What should i do for my 1st gaming PC, i have around a $1500 limit and people are telling me instead of getting the 4 gb 680 which i originally planned, just get the 770 and instead of getting the i5-3570k people say just get the i5-4570 since i wasn't looking to overclock, but should i overclock, is it worth it? because i want this to be a monster but i don't want it to break, and if i should overclock how does it even benefit me? also are there any other recommendation for a GPU and CPU?
