The MSI RX600XT-TD128 flew through all the benchmarks we ran, and performed quite well at 1024x768. Higher resolutions might be out of the question depending on the application, but if you find the card a bit slow, simply overclock it. Our particular card was able to hit a very respectable 610 MHz core, and 438 MHz memory. Despite the added stress, the MSI RX600XT-TD128 is completely silent during operation, and you will not hear it when it's installed into a case.
