I'm a Mac user, just sitting on the sidelines listening to this PC talk.
I used to game on Mac's back in the day(90's *cough* man I'm old), but their quality, much less price compared to other PC makers is horridly bad. One can argue they dropped Computers from Apple's name because they're not exclusively a Computer maker anymore but I think its because their computers aren't the value that they once were(80's and 90's PowerMac's were pretty dope. Now they're overpriced paper-weights).
I hope to build my own computer in the coming year or so because Windows 7 support is slated to end(forcing a rig update). Thinking along the lines of the following components:
CPU: Latest and greatest AMD Ryzen(thinking 3900X but who knows). I will give Intel a very strong look with regards to their 10nm CPU's that they're
finally starting to bring to market but are limited to Laptops right now. Wanting to see what their PC 10nm CPU's would bring to the table and at what price(typical Intel being quiet on it because they have nothing to say. Otherwise they would have by now to try and fend off AMD).
Motherboard: Basically whatever I pick for CPU, I have to pick a compatible Motherboard. Probably will go Gigabyte or MSI in this department.
RAM: DDR5 RAM is nearly on the market(2020 was the earliest I heard) but odds are I'll go with 32 GB of DDR4 RAM(2666 MHz speed or faster if the CPU can support it). RAM maker really doesn't matter all too much.
GPU: NVidia RTX 2080. Bit of a splurge I know but I want to get something that will last me for a solid decade and this card ought to do it. It's come down in price since its release so when I finally get around to actually buying components, the price won't sting as much. I might downgrade to a 2060 if I want to save a bit of $$$.
Case: Full Tower case to fit everything
Cooling: Closed-Loop Water Cool kit. Been wanting to do one and with today's components, Water-Cooling is almost a must because these components are Energy hogs and hence generate gobs of heat.
Hard Drive: 2 x SSD's. One for Operating System and games I play often. Other for everything else. As for size, thinking 500 GB for first one and 1 TB for 2nd one. Might get a 3 TB storage HDD as a backup.
Monitor: 27-31 inch 2560 x 1440 resolution(or better), 144 Hz and 1-4 ms response time. There's literally 8k Monitors out there but I can't see a reason to go anything beyond 4k at this point in time.
Right now, the above pushes $3k(if not more). Keep in mind that the computer I'm typing on right now is circa 2010 with hardware even older than that. I'm
way overdue for a new rig.
