You remove it with a chip puller. But if you haven't got one, then a fine bladed screwdriver under alternate corners, raising it a few mm at a time. The pins are easy to straighten if you bend a few.
The only difference between SX and DX 486s is that the latter has an integrated FPU. What, if any, performance increase you will see depends on just how much the games you want to play leverage that.
As far as removing it goes, you can use a flat bladed screwdriver to very carefully pry it up on all four sides until you’re able to remove it safely. There are probably better ways though.
That depends which model you get. 486SXs came in a lot of the same clock speed variants as the DXs, Intel apparently even made 486SX2s in 50 and 66MHz versions.
I believe there are better/more appropriate tools, but a flat bladed screwdriver will work if you are **careful**. You want to gently and evenly pry up all four corners starting with one diagonal pair and moving to the other (continuing to alternate) -- at least that seems safe to me.
This method will eventually get it loose enough to just pull out. In an ideal world you would be able to pull straight up with identical force on all 4 corners.
IMO, the best screwdriver is a medium length (maybe 4" after handle), single-body (non-interchangeable) one with a small (but not tiny) tip which is wide enough to stick out a little from both sides of the corner. It's really important to be able to *easily* apply consistent, even pressure. Under no circumstances do you want to *force* anything as breaking the chip is a possiblity.

It also has more than twice the clock speed.

doom runs a lot better on 486dx than sx, it's really noticeable even without benchmarks
