This card comes with a replacement Asus AMD 7850 2Gb on an HP Z400 computer. I have greatly gained in performance. For example: Far Cry 4 is passed (with the same fluidity) from "high" to "ultra". Assasin Creed Unity is almost as fluid as on a PS4. I am extremely happy for the price. However, only in play, and even the older games, I find it noisy. The 2 large fans evacuate watts, it shows. Most: NVIDIA is still 2 Gb Finally, attention to diet that requires two connectors (adapters supplied).
