Don't worry GPNZ, Richard has you covered
Interesting tidbits that digital foundry found for us
* The 4k home screen was scrapped, the entire system UI runs in 1080p, the 1Gb of memory that was supposed to be reserved for a 4k output to the UI was removed and instead reserved for games, developers told MS they had to use that 1GB of memory for the games so the UI will now continue to be in 1080p
* The system is still CPU bottlenecked, heavily so - in DF's testing even games like Gears of War 4 which has a 60fps mode can not maintain 60fps (drops down to 40fps were observed) and CPU bottleneck can easily be measured in system draw load - for instance the One X draws 175w when playing Gears in 4k mode but only draws 125w when playing in 60fps mode, the system is unable to use an extra 50w worth of power as the GPU is patiently waiting for the CPU draw calls to process - the same was observed in other titles as well - in Just Cause 3 the game stil frequently drops under 30fps on the One X during explosions
The One X is a great console to match a 4k HDR TV, a solid upgrade for anyone owning a one s or one
Whether or not it makes sense for a PS4 PRO owners to jump ship, well maybe not but it could be worth owning both systems - on the one hand you have GPU limited games that can take advantage of that GPU tflop boost to produce resolutions closer to native 4k and sometimes higher quality textures which is awesome, but for every one of these games, you also have CPU limited games which will continue to run with performance only slightly better than the original Xbox One
