I went with mWave in Sydney, picked my parts and they put it together for me - ran Witcher 3 at 30hz just fine, mind you this was the gen 4 i7 processor days

Just bought an MSI mid range lappy I'm generally happy about, though it means lower resolution settings - it's still got enough ram to record gaming, do the vid editing, plus serves me as a writing station when I stop playing games for a bit, $600 off

It can do 1080p but boy it puts out some heat
