For a week now the card in my system (i5 CPU, 8GB of RAM Gigabyte, motherboard) is installed, replacing a Radeon 4890. All tested games run best settings Call of Duty Black Ops 2, Crysis 3 etc ...... The "classic" pose no problem. The heat development is only a fraction of the former Radeon 4890. The noise level is a normal residential environment (not soundproof room) barely perceptible. The power consumption is significantly lower than the old Radeon, thermally I can bestätigen.Sie also requires only one additional power supply instead of two. To sum up: best perceived gaming performance in very elaborate games in best settings on 23 inch FullHD display. Can you hesitate to recommend. Because it makes no sense to spend more money (for normal gamers) - not to a few frames to get more power to only using trial software visible!
