Today we hear that Mushkin is now working on an UltimateFX version of the Radeon HD4850. The new Radeon HD 4850 will feature a completely custom build. The cooling system looks a lot like the one found on the Sapphire HD4670 offering though. Specs are; 800 stream processors, 256-Bit memory interface, 625MHz/1986MHz CPU/Memory stock clock and 700/2020 for the OCd version. There will be three ports for output (DVI, D-Sub and HDMI).
All this will come in a handy wooden box. There is no indication on when you can get these nor how much they will cost you once ready.
