I bought this card when it was the best in the market (approx 2 years ago). It's a powerful card. However there are some sever overheating problems with it. I can run games for approximately a hour and a half before there are some sever graphics problems. Textures start messing up, and frames start skipping. Frames per second go from 50+ on games like unreal tourney 3 and tabula rasa to 5 fps, making the game unplayable. The only way one can continue playing the game is to allow the computer to cool by turning it off for approximately 10 minutes. There are no drivers to allow you to see what temperature the graphics card is at, or how to fix this problem. I have heard other BFG cards are good, however this OC card has sever problems.
My suggestions are that if your going to invest in a graphics card, avoid BFG, solely for the fact that the driver are poor. If you have a good cooling system, this card may be worth it, otherwise avoid this card.
