Hi I am relatively new to pc gaming and my first time building my own pc. I have an asrock a75m mobo, an a6 3670k cpu and planning on getting either a R9 280x or R9 290, and 8 gb or more of ram. So my question is will i be able to play newer games at high/ultra setting? Or some older games like skyrim with some graphics mods? I appreciate any input.
