Hi everyone im kind of new to building pc's and its my first build. I have an asrock a75m micro atx motherboard an amd a8 3870k apu and planning on 8 gb of ram and a radeon r9 280x gpu. My question is if you guys think this would be sufficient enough to play some of the newer games on high/ultra or some older games like skyrim with some graphics mods? Thanks for any input!
