PowerColor Radeon HD 5750 Review
 

Performance at stock was right about where it should be, there weren't any surprises. The 1GB of memory helped out in some games at 2560x1600 while others the card was just too weak. Once the big overclock set in though, this card was a performer! It wasn't ground shattering, but it did help the 5750 catch up to the other cards and made it feel less like a low-midrange GPU.
