Referring to only SATA, a bit of a noob when it comes to SSD.

I am buying a new SSD, but I'm unsure which to choose. I see Mushkin give value, but I see a lot of people buy one of the Samsung EVOs or SanDisk Pros. Aside from amount of storage, what are all the differences and would the choice impact something like GTA 5 @4k signifigantly?

Do not be much swayed by vendor synthetic SSD benchmarks.
They are done with apps that push the SSD to it's maximum using queue lengths of 30 or so.
Most desktop users will do one or two things at a time, so they will see queue lengths of one or two.
What really counts is the response times, particularly for small random I/O. That is what the os does mostly.
For that, the response times of current SSD's are remarkably similar. And quick. They will be 50X faster than a hard drive.
In sequential operations, they will be 2x faster than a hard drive, perhaps 3x if you have a sata3 interface.
Larger SSD's are preferable. They have more nand chips that can be accessed in parallel. Sort of an internal raid-0 if you will.
Also, a SSD will...

SSDs do not impact game performance in any way apart from loading time, as they are just faster storage drives when it comes down to it.
If you can afford it, something like a 250GB Samsung 850 Evo is optimal, as it will give you great read/write speeds at a competitive price.
If you're more on a budget, get the OCZ Trion 150 240GB or the A-Data SP550 240GB, either is a good choice.
Just because a drive is listed as hitting a certain speed, it does not mean they will perform this way consistently, never trust spec sheets for SSDs, and always read reviews.

Also, a SSD will slow down as it approaches full. That is because it will have a harder time finding free nand blocks to do an update without a read/write operation.

That said, I think Samsung and evo make the better ssd devices today

If you have any doubts, check the newegg reviews from verified buyers.
Samsung 850 evo will have almost no valid negative 0 egg reviews.

There will be little impact on gaming.
Mostly from game load times and faster game checkpoints.
But everything you do will feel much faster.
I will never again build without a ssd for the C drive.

In terms of windows massive when booting from it can cut boot timw more then half



Games will load faster too and in large open world types games should have leas stuttering when moving from one area to another
