well Hi10p isn't stupid per se, it's just that nobody ever thought of using the standard for computer coding/decoding hardware...
So people wake-up to the simple truth it has always been there ever since the avent of the H264 norm.
But it's true that a simple i5, although quite expensive, should give me some headroom for 3-4 years and then a simple GPU of the time might be able to extend the lifespan another 3 years. It's too much of a time period to guess what the video world might come with. Although 4k and 8k standards are there already. But for anime that will clearly be overkill, as is 1080 for screens up to 42 inches.
Since I can wait some months, January rebates will come in handy I guess.
Thanks
