3 out of 5 eggsBeware one DVI port is a DVI-D port

Pros: The card is well constructed and the performance is what I expect from the ATI 7770 chipset.

Cons: Although the card has two DVI-I physical ports, the second port is wired to only provide only a digital signal. This means that you cannot connect two analog monitors to the card using DVI to VGA adapters because the second port only carries a digital signal.

Other Thoughts: I bought this card specifically because the pictures showed that it had two DVI-I physical ports and I did not want to have to upgrade my monitors or purchase a display port to dual DVI-I adapter in order to keep my dual display setup. I was disappointed to find out that although the card allows two DVI to VGA adapters to be physically connected, one of them will not function because of how the card is wired internally. If I had know about this limitation before making the purchase, I probably would have purchased another card and a display port to dual DVI-I adapter,

5 out of 5 eggs@Phony rebate

Pros: You sir are the complete bane of reviews. You submit a review on a video card based on how the card performs, whether its complete crud or the golden-boy of cards. You come here, and 1 Egg this based over a $20 rebate?? Really dude, get it together and delete your review, it's complete crud and it does nobody any favors. This is a product review, not a place to whine about NOT getting a rebate, has nothing to do with the product.

Cons: n/a

1 out of 5 eggsPhony rebate

Pros: Good card - no question.

Cons: My beef here is that I bought this particular card because it had a rebate. Well, come to find out that the website for Diamond is complete inaccessible. So, I couldn't even register for the rebate and now the time is up. I tried it on 4 different computers with varying versions of IE and got half a screen - that's it. So, yes, I am holding a grudge because I feel that they owe me $20.00
