Far Cry 2

Far Cry 2 requires plenty of memory and bandwidth, which is evident from the following tables. The HD 5750 with 1GB of GDDR5 memory performs much better than HD 4850 cards with 512MB of GDDR3 memory. Mushkin's card outran the reference HD 4850 by about 5%.
  

HAWX

HAWX shows the benefits of HD 5750's additional memory only at the highest resolution, which matters little because the result is only 29 fps. Mushkin's overclocked HD 4850 OC wins in this test, leaving the reference HD 4850 behind by up to 8%.
