I just did my first build and it is a MSI g46 mobo,fx 8320 CPU, 8 GB of ram, MSI HD 7770 with a 500 watt psu. Looking online I keep seeing all of these videos showing people playing these games on ultra or maxed out settings and the majority of them seem a little choppy. So my question is if I upgrade from HD 7770 to a r7 260x or r9 270 is it going to be much better or a slight change to better?
