Conclusion:
The Sapphire TOXIC 4870 seems to nail directly the major grievance of all the 4800 cards: heat. This is no longer an issue with this card and it does so without adding any extra fan noise as well. Put this together with the performance of the 4870 and a good bundle and you have a definite winner. Plus you get a nice overclock and much more headroom for overclockability. If heat has been a major reason you've avoided the 4800 or you won't one that runs cool out of the box, look no further. I can say from personal experience stock 4800 cards, especially 4850's run too hot out of the box so this is good news from Sapphire and for ATI!

Pricing:
We can't find the card at e-tailers yet online but the normal Sapphire Radeon 4870 can be had for $279 online. Hopefully the TOXIC can stay somewhere around this range perhaps with a rebate.
