TheTechLounge posted a review on the Sapphire Radeon HD 4870 512MB TOXIC Video Card

I think it's worth everyone's wait for Toxic. As far as brandings go, anyway. But Sapphire puts so much effort into general improvements over the stock designs--which they have no small hand in-- that I have to wonder if they hold back just to make certain that their Toxic will be that much better. Maybe I'm giving too much away for an intro. Let's get back to boring stuff, like how HD 4000 changed every possible standard for pricing, and slammed into NVIDIA's market share so hard that they knocked stock out of 'em. People walking past their offices in California were picking it up on the streets as souvenirs, "I was there when HD 4000 was released!" HD 4870, the flagship, wasn't a hundred percent, though. It uses a lot of power, and makes a lot of noise. I don't expect the efficiency to change, but I, and silence enthusiasts everywhere, have been rubbing their hands in wait for Sapphire to throw in their characteristic blue into the equation.
