I have a motherboard/ram/cpu combo from a prebuilt system, everything else is upgraded. The CPU i have is an i5 4430s, an asus prebuilt specific motherboard (looks like a h87m PRO) and 12gb (4+8gb) of adata ddr3 ram. I'm currently wondering if i will run into any issues if i swap out the i5 4430s with an i7 4770k (found a shop that still has one). I know i wont be able to overclock, but will it be able to run or are there some issues?
