OP is missing the fact that consoles have 10 year cycles. So yes it might be (almost) on par now, but in 5 years time OP will be sitting with a bunch of games made for 5 year old tech that was medium range even back then.

Maybe it makes sense to some but the plan just leaves me scratching my head. Personally I prefer buying one really powerful device - then I've got power for all the tasks (gaming & other), versus 2 medium range devices.

Bit pissed about SA hardware prices right now though.
