How do you mean "hold up"?
The Samsung 830 probably won't compete with the latest and greatest on benchmarks, but in normal day-to-day use as an OS drive, I doubt you'd really notice much difference between them - it'll still be much quicker than a HDD!
If you can get one for $90, it looks a bit of a steal TBH when compared with others - eg the 120GB DX Mushkin you were considering, which is $185 - I know where my money would be going!
