Ok, it's 2019 and I still rock my MP5.1 with its stock ATI 5770 and its 4-cores 3.2GHz. I have not any impelling reason to upgrade to 10.14, but I noticed that when I play via bootcamp my PC games (mostly indies and strategy games, I have an Xbox for the big titles) the performance of my 5770 begins to falter. So, in the end, I've decided to inform myself about the possible upgrades, and this is my doubt: I better -buy a GTX 970 flashed to show the bootscreen and sell my 5770, or - buy a stock brand-new GTX 1650 and installing beside to 5770? In the second case, my doubts reside in the power consumption, and possible incompatibilities on the Mac side. Thanks for reading.
