I've upgraded my Graphics Card to a GTX 2070 8GB DDR6 from a 1050TI 4GB, the rest of my specs are 32 GB of DDR4 ram, a x470 gaming motherboard, AMD 2700X 8 core processor. 850W power supply. I have a 60Hz monitor but I'm looking to upgrade to a 144Hz monitor this Christmas.  What do you guys think of my build?

That's a pretty decent pc you have yourself there rock 
I have an evga rtx 2070 super paired with a ryzen 5 2600x but only 16gb ram and a 700w evga psu all connected to a rog strix b350-f gaming mobo

I'll trade ya..
