Hi, I want to buy a 144hz monitor but I dont know if my GTX 660 would support G-Sync and 144hz gaming. I am also planning on upgrading my GPU but currently I dont have enough money to buy both the monitor and the GPU. So, what do you think? I know that whatever I buy (the monitor or the GPU), I will not be able to enjoy the full capability of it until I buy the other one. But, what should I buy first? I also have a i7 7700k, 16gb ddr4 2400mhz and a Maximus VIII Ranger.
