Sapphire Radeon HD 5970 TOXIC 4GB Video Card (Page 3)

The Card





The card is huge; well, when we say huge we mean it takes up three slots instead of the standard two. Overall, it's not really any bigger than a standard HD 5970. In saying that, though, the fact it's got three massive fans on the cooler makes it look and feel so much bigger than it actually is.

While the I/O shows no changes with the two Dual Link DVI connectors and single mini DisplayPort being present, the big difference about this card compared to other HD 5970s is the fact that it requires two 8-Pin PCI-E power connectors instead of a single one alongside a 6-Pin. For most people this isn't going to be an issue, but in saying that, it's clearly something worth noting.



When it came to checking the clock speeds I had to double check one of my previous reviews of a HD 5970 to make sure I was reading the overclock correctly. Even after I checked one of my older GPU-Z screen shots I googled to triple check that I was seeing the overclock right.

The 900MHz core clock is 175MHz higher than the stock HD 5970. As for the GDDR5, that's gone from 4000MHz QDR to 4800MHz QDR. If that wasn't tickling your fancy, how about the fact that that 4800MHz QDR clock is for 4GB of GDDR5 instead of the standard 2GB?

If there was ever a card made for triple monitor Eyefinity gaming, this is the one!
