The general rule for semiconductors: you are fine as long as the magic smoke hasn't escaped. If it had escaped, you would be writing about how your GPU either appears to be dead or might be causing issues you didn't have before.

There is a concern about the long term viability of any electronic component. Two issues:
a) Thermal Cycling - The wider the range of the cycle, the more physical stress is on the micro circuit traces... running at 90+ for hours than dropping to 20 means my cycles of thermal expansion / contraction and this is what you want to avoid from both Frequency and Range perspective
b) Heat / Voltage - The space between individual microcircuit traces is very small. The ability to board and chip to insulate the individual circuits from one another and prevent signals from crossing through decreases with both voltage and heat over time.
So as a PC users, you want to minimize the amount and range of cycling as well as the total number of hours at elevated temps .... your "few minutes" has no impact here.
