Gurm so jealous, I have been trying to scrounge up an early 2013 MBP for a long time.
Yeah. To be honest I really do feel that somehow I lucked into this model working oh so well for me. Occasionally I've used other laptops and the eye strain can be dreadful. The same thing applies to my GTX970 video card at home. Every single newer card I've tried (980, 980Ti, 1070, 1080, Vega 64) is no good for me. Hell, even the "same" GTX970 card but one hardware revision newer, or with a different brand of RAM, is no good. I could also argue the same with my Dell 2407 monitors. Most other monitors I've tried have been no good. Still - endless trying out of new stuff and losing money on every deal is very tiresome and immensely frustrating.
I so so want a faster video card and a bigger screen...! Argh! (I have a hankering to 'try' an Nvidia 2xxx card but I know I'll likely just lose even more money).
