Sapphire's Radeon HD 4850 X2 launched back in November '08 and remains the one-and-only 4850 X2 in production. If you've already picked one up, and you're now wanting to overclock the hell out of it or just make it as quite as possible - you can, thanks to XSPC.
The UK-based water-cooling specialist has announced the availability of its Razor 4850 X2 water block, bringing enthusiasts the opportunity to water cool Sapphire's dual-GPU card.
The Razor 4850 X2, pictured below, is said to have been co-developed by Sapphire and XSPC and is made from CNC machined copper with a CNC cut acetal top and aluminium VRM cooler. Should you be wanting to double up with another 4850 X2, it's CrossFire ready with four threaded ports.
A useful solution for those wanting to put Sapphire's Radeon HD 4850 X2 into an existing water-cooled system, but current pricing might deter would-be buyers. XSPC prices the Razor 4850 X2 at £74.99, and Sapphire's 2GB card is currently being sold at SCAN.co.uk at a cost of £227.46.
That's over £300 in total, and with recent price cuts, a stock-cooled but notably-quicker Radeon HD 4870 X2 can be found for just £240. On the other hand, if you're already got your hands on a 4850 X2 and you insist on water cooling it, there really aren't any other options that we know of.
