I think i put an ssd for all builds since that will boost by a lot your system boot and apps, at gaming it will improve loading times, put fast ram on the more expensive cpu/mobo configurations since benchmarks showed some benefits on both platforms, did not include a cpu cooler on the amd combo cause that cpu comes with a capable one. You should modify any of the lists to suit your preferences on brands and models but those are 3 pretty reasonable upgrade paths you can consider.
