Yo. I have both of these cards. I'm not sure which to keep, so maybe you guys can help. 4890 1GB: Pros: Smaller card Cheaper water block Pretty good specs and power consumption Cons: Not an X2. 4870 X2 2GB Pros: Was Uber until a week ago. Cons Expensive water block (twice the price of the 4890) High power consumption So, which would you keep, buy a water block for, and use?
