There are a lot of positives to the ATOMIC. Performance for starters is way up compared to the stock model and we can see some good gains; the best being seen at the higher resolutions where a large amount of strain is placed on the graphics card. We also have a pretty good bundle included, an absolutely kick ass package, an excellent cooling solution on the graphics card and also the fact the card is a limited edition model which is numbered, just to make you feel a bit more special as an owner of one of these beauties.
The Asetek cooler, on a whole, does a good job of cooling the card; unfortunately it doesn't look like the same could be said for the CPU portion. While the concept is cool, it does have some flaws; the integrated CPU cooler and the way the system is designed makes going to Crossfire pretty difficult. Of course the other con is the price of the card; at around the $600US mark it's not cheap by any standard.
If you get past these cons, though, you really do have the fastest single card graphics solution we've tested to date and that is ultimately what Sapphire wanted to achieve. The only thing we probably would have preferred to see is the CPU cooler not included, especially since a 1366 bracket for i7 CPUs isn't available.
All in all, the HD 4870 X2 ATOMIC is a fast card and like anything that pushes the boundaries, it does have some cons. But ultimately performance talks and Sapphire has managed to make a very quick card here.
