You'll need much faster RAM, 3200mhx and possibly 3600.
You'll want an M2 drive, better PSU, some cooling and things like the CPU I dont have enough expertise to know if its overpowered. but it probably is.
But spyder is the person to help, so if you post the full spec and the link to edit...
Cancel and wait for the G9 to come into stock.
It's the newer version of the one you've ordered and spec wise quite a big leap, for not much more cash.
Change the motherboard to the 550 and up your ram to 16gb 3600mhz possibly. I don't know enough but as Stephen said you will need more ram. The rest looks good, but will need people with far greater knowledge to take a look.
There are a few things that need looking at and changing. Your motherboard for one, you really need a 570 with that CPU. The cooler might also not be sufficient for the CPU and these two things could lead to problems.
I think you can save some money on the GPU, overpowered for your monitors I believe, the AMD stock cooler will be good enough if you're just gaming and you don't need extra thermal paste, the standard is good enough. Regarding the GPU I don't know which one, but someone will be able to help you...
I don't know much, but a few things I do know: You'll need a better motherboard for that CPU, one of the 570's and probably the strix. The cooler you want one of the platinum coolers at the bottom.
PSU up to an Rmx version, WiFi up to ax200.
Stuff like the the case, CPU, ram and GPU I don't...
I have this case and cooler. It is an excellent combination and obvious why the two are recommended so much. Quiet, cool, room for upgrades and so happy with both.
