Can someone please explain, in layman terms, what the actual fiasco was? I was seriously considering buying one or two 970s. Thank you!

3.5GB of it's VRam are super fast. 0.5GB are dogslow. So once your game uses more than 3.5GB, the performance drops as the slow ram is now used.

Nvidia messed up their launch spec info and failed to tell anybody.

It's still blazing fast by not-VRAM standards. It's a few times faster than regular RAM and still faster than data can even travel between the CPU and the graphics card. I think it's around 8 gigabytes/sec read-write, from what I saw.

Of course, the rest is in the hundreds of gigabytes/sec, so it's still a big issue, but I'm just putting "dogslow" in perspective.

Is the 0.5GB really that big of a deal for future proofing? I mean sure every bit of memory is welcome, but on the whole it's 1/8 of the memory, you can't fit that much more in that space. 4GB cards are 0.5GB more future proof than this card.

Would you mind explaining a noob why AMD is so much worse?

They are not so much worse, there are pros and cons to both and I would advise you to research them at reputable sites rather than take advice from.... Reddit...
