Thanks for the help so far!
maybe you should wait for the new RX 480 cards, they are just around the corner..
and for PSU I would recommend any seasonic build PSU.. it doesnt have to be seasonic brand, it can be corsair or xfx.. just read the reviews before buying to see which actually is build by seasonic..
good luck with your venture..
Thanks! Am I right in understanding that a 600W PSU would suffice for this rig?
