With the recent arrival of the new ATI Radeon HD 5 series graphics cards causing a great deal of interest, the previous best performing single GPU from ATI -- the 4890 -- has been left by the way side a little. Although, on the whole, the ATI DX11 GPU launches have been a great success for ATI, many users will still be sticking to the 4 series, if not older, cards and as ATI seeks to monopolise the DirectX11 Market with nVidia's Fermi Technology lagging far behind, it's definitely a good time to be investing in a 4890 or other 4 series GPU.

To further the lure of the 4890, ASUS have been quick to beef up the card with a unique cooler allowing for increases to both the memory and core frequencies. Being part of the "Formula" series is essentially equivalent to Sapphire's Vapor-X or XFX's XXX Edition cards whereby the stock 4890 is overclocked and tweaked to ultimately create a better, more unique card. Let's take a look.
