There's too many fake flags around here, so I've got to ask: In which country are you actually going to buy the parts?
If you're actually in the Philippines I'll need a link to a shop, or even better to a price comparision site.
I'm guessing it's not urgent, so I'd wait a bit for the Zen 6 and 4 core CPUs.
What fps/settings/resolution are you going for?
Do you need peripherals? Monitor, mouse, keyboard, etc.?
And now you see why I told you to wait. Twice the cores for 330$ is quite a difference.
It's still a week until the actual release so pcpartpicker doesn't have mobos listed yet and it wouldn't make a difference anyway.
And yes, the 1700 was what I planned to go with anyway, once you said you want multitasking and multiple VMs.
Now you probably don't need a high end GPU for light gaming, but any particular minimum requirements for software with GPU acceleration? Do you need/want CUDA? Double precision?
Oh and just so you know: Siemens is planning on upgrading a lot of their systems. Guess what they are upgrading to. Sweet, sweet Zen optimizations coming for Siemens NX.
