TheTechLounge posted a review on the Diamond HD 4870 512MB video card
The 4870 is an excellent card, but for now, all the models are functionally identical, and there are yet to be factory-overclocked cards, let alone custom-cooled models. Variation ranges from changing the sticker to adding spiffy adapters. If you buy Diamond, you're not buying a different card, you're buying better service, only they're not charging extra.Diamond HD 4870 512MB Review
