Hi Tech Legion posted a review on the Diamond HD 4870 1GB GDDR5
The Diamond HD 4870 1GB GDDR5 was one of ATI's most powerful cards on the market, until just recently, with ATI's new 4890 coming out, and the HD 4870 1GB GDDR5 by Diamond is still a great card to own and purchase, especially with some recent price drops. The Diamond HD 4870 can be part of AMD's Dragon Platform, which is definitely a plus to anyone looking to upgrade to a Phenom II.Diamond HD 4870 1GB GDDR5 Review
