The HD 5970 TOXIC 4GB
It's awesome to see that Sapphire has chosen to include both a Dirt II and Modern Warfare 2 voucher; one of the best game bundles we've seen in a long time.
On the card front we'd seen pictures around the net of it and the cooler is as huge as it looks in those pictures. The massive three-fan design is also a triple slot cooler, so running CrossFire X might be a problem for some, depending on your motherboard.
On the clock front the card is impressive...and I mean impressive! - Considering the stock clocks on a HD 5970 are 725MHz on the core and 4GHz QDR on the memory, we don't really need to say much else.
