Page 1 of 3 We will swiftly skip the packaging and bundle part, as there is none – this is a referent sample, so we gladly move on straight to the card itself. As always, we are dealing with a red-coloured card, which is obviously a product of some serious work. Although HD 2600XT Dual impressed us both in size and in performance, we admit that we never expected such a huge improvement in such a short time-span. The new card is better by leaps and bounds – the card has a lower profile, nearly identical to the regular version of the HD 3870.
The length of the card remained unchanged, but this is a compromise which simply had to be made; we are dealing with two cards on one PCB after all. The cooling solution is also very elegant, in the form of a massive, large-scale cooling profile with a single fan. We were a bit surprised that there is only one fan, but it turned out to be more than enough, and not particularly noisy either, especially when compared to a 2900XT, for instance. Naturally, it is a dual-slot solution.

The card is very firmly built, quite possibly even the most one so to date, which means that everything is tight as it should be, in a word – excellent. The card has standard connectors: two DVI and one D-Sub connector.
