I just saw the 9800x2 go on sale at Scan in the UK.
At £400 mind, I think I'll stick with a 9600GT or 8800GT, but for crazy high resolutions at warp speed frame rates I don't think you could buy better. 4x9800 in SLI!
The 9xxx range is also supposed to be greener reducing watts used when just surfing the web or in word but looks like you have to buy a nVidia motherboard as well
