Bad performance due to badly flashed bios?

[xFluing]

Can a badly flashed bios affect the performance and/or thermals of a card?

 

Here's some back story

 

About a month ago I bought a Sapphire HD 7850 second hand, and it had great performance, but lacking in other games (such as SS3 Fusion or Borderlands 2) I didn't think much of it, I thought it was a CPU bottleneck doing that, but recently it got some power delivery issues, and the guy was kind enough to give me an MSI as replacement (same model), only 1GB in memory though, but it runs much cooler, by about 10-15 degrees, and it performs much better to my surprise: where I couldn't really play SS3 or Borderlands in 1080p above 45FPS average, now I can play both of those in 1440p60+ (same exact settings) no problem.

 

The day I took the card back is when I found out the Sapphire had been flashed poorly by somebody else.

I don't think flashing a bios so called 'badly' would cause performance issues. Maybe they did something else behind your back.

Who knows? All in all Im kinda glad the other one broke down because now I feel I unlocked the true potential of this card.
