SAT Physics: Will a 790 or 800 make a difference over a 750 for top colleges?

I got 750 in SAT Physics last June. This month, I’ll be busy with my college applications (and I’m going for early action and I’m aiming for top colleges), but I was thinking of taking the November 7 SAT Subject Test in Physics. This would by my second time taking the test. My knowledge was a bit lacking when I took the first one (and got 750), and I think I can get 790-800. If I manage to do that (it would take some effort), would it make a difference in my application? Or should I forget about it and go with the 750? My GPA is 4.0 but from an unknown school in an international country. Would an increased SAT Physics score make a difference in the weight of this GPA or in how they see it (since it would increase credibility of this 4.0)?

For what it’s worth, I got an 800 in SAT Math Subject Test Level 2 last June.

Thanks a lot for any help/suggestions. I appreciate any thoughts.

Since retaking would require effort to study and such, don’t do it.

Essays are way for important than SAT 2 tests so spend time on those instead of a SAT 2 subject test.

750 is perfectly fine for any school.
