SAT Score - good enough or not?

Applying to College
1

October: 2210 (660R, 770M, 780W)
January: 2290 (740R, 800M, 750W)
Superscore: 2320 (740R, 800M, 780W)

Are these scores good enough for:
Berkeley (single-sitting)
UCLA (single-sitting)
Ivies/Mit/Stanford (superscore)

or is it worth taking the ACT? and if so then what score on ACT would be sufficient

@monkeybeaner Yes those are fine. The SAT is not the only factor determining admissions, nor is it the most important factor.
