Graphic card is beautiful, very silent, very cold, my previous 4870X2 was very noisy and warm, always with software and hardware problems, 5870 runs very smooth on both systems, and no problems so far, I have it 2 or 3 weeks now, performance is better with AMD but the difference is very small, both systems are very fast, Intel don't have fps drops like AMD but overall I like them very much, Intel also have shorter game load times, overall I'm impressed with 5870, it beats 4870X2 in any aspect, I will never buy X2 graphic card again
