Conclusion: I really like this card, in my opinion this is the 9800GTX killer. We’re talking a card that costs around 35% less but giving 95% performance and sometimes more! The HD4850 cards are heat generators. NOTE : this applies to ALL cards regardless of brand. From my point of view, I wouldn’t worry until the card is showing signs of overheating. Heat is not a major issue though, just a little knowledge in finding a file and editing it can do wonders.
