Just got some money around and going to spend it on my computer upgrade. After already update my CPU to 3700X, I have a little bit of difficulty to choose which graphics card should I buy, after all, the brand new RTX2070 Super, the RTX2080 or a second hand 1080Ti OC? They cost pretty much the same and so does their performance (through checking on the internet). Right now I have 144Hz at 1080p but planning to get a new monitor with 2K 144Hz. Thus among all three which card is the best for me?
