Well, that would be whichever one you plug into first, really.

Lookup the Rode Smartlav+ on Amazon, also make sure you grab the necessary adaptor to plug into whatever you're streaming from

That source selector you linked will probably do the job just fine. For what you want, the all passive design is a good way to and RCA to 3.5mm adaptors are quite affordable.

I tried learning C++ as my first language but I've since put that on hold to focus on Lua first. With Lua, I've had a lot more fun learning to program and it's also quite useful for me as I work with some systems that work with embedded Lua scripts for advanced control purposes. I think it would be much better going for Java/Lua/Python first as that will give you and idea about how programming works and many of the skills are somewhat transferable.

DDR2. Literally took me 10 seconds to google.

It's just USB ports on the motherboard that deliver more current than the 500ma supplied as standard. It will usually be 1 amp or so, and it cannot be done in software as it's hardware based

Seems to me like the wire that splits into headphone and mic to plug into the motherboard has gone bad, if it's replaceable and not fixed into the headset, I'd just contact their support and see if they would send you one. And even if they didn't, they're fairly cheap on amazon.

I dug this up quick: http://gpu.userbenchmark.com/Compare/Nvidia-GTX-1070-vs-AMD-RX-480/3609vs3634 If you're happy with the RX480 based on those numbers, and assuming you are going to be playing the same games in the time you want to keep the card, then there's no reason you couldn't. However, it's unlikely you'll be playing the same stuff for 3+ years so I'd naturally be leaning over to the 1070 regardless. Edit: I misread the post, but my response still sides with the 1070 for longevity

But a 1070 over a 1060, kept for a long period of time represents a better overall value, no?

As in, render 4K and down sample to 1080p? (sorry, I've just woken up) Yeah sure. It would also give you a nice path to go for a higher res monitor in the future if that's something you'd be interested in.

At 1080p you would get more than 3 years out of it, I only yesterday bought a 1070 to replace my 4 year old 770 and that was only because 2GB of VRAM was not enough anymore. I also run at 1440p.

It says there are 2 sticks of 8

I would make sure that everything is as it should be in Realtek Audio Manager- I can't look for anything in there myself because my board doesn't have a Realtek chip. Failing that I think the best option would be to grab one of those cheap USB soundcards and use it for the microphone

If a single amp channel is rated at 6-16 ohms, one of your speakers rated at 4-8 will probably be OK. But, if you add speakers to that amp channel, the impedance will drop, and when that happens it will increase the current draw and it may get to a point where the amp gets too hot and dies. If the speakers you are adding will have their own channel, that's fine. If not, see above.

Ah, that's a spot for a surface mount resistor. But I would agree that because this stuff isn't really designed to be serviceable; a repair would be quite tedious.
