those day desktop GPU really much much more performance than mobile GPU. but no longer seen in GTX10 series , simply pair with GTX1050Ti , GTX1060 will perform like a desktop graphic.
it's better come out the PC using notebook motherboard , ram , GPU even power supply using DC type instead of ATX power supply. just omit the keyboard , and display . remain the small amount battery (30-60 mins for backup usage , as UPS function ) add more USB port . it's will be perfect . I know DIY user think to change GPU in future , actually when i after using 6 years for my PC , simply upgrade the GPU the CPU wouldn't help u bring up the graphic performance. Maybe soon MXM GPU will be the future desktop PC GPU standard.
