Hey, I custom built a computer about a year ago, and recently have been noticing my graphics card isn't completely up to par with what I thought it would be. I am somewhat new to the whole custom building world, and need some help. I'm hoping to upgrade my graphics card to something newer, and am wondering if I am going to need to upgrade any other parts of my rig so that it can support something along the lines of a GTX 1070. or something alike. Currently I am not looking to spend a lot of money, I would like to spend just enough to support a stronger graphics card.
6300 will definitely hold back a GTX 1070 in newer titles, it's just not all that powerful anymore when compared with more modern (read: Intel) offerings. Unfortunately due to the socket it's on, you can't really upgrade without changing out the motherboard and maybe the RAM too.
So.. new (or secondhand) motherboard, CPU, and RAM (if going Skylake). PSU/case/etc should be fine.
