Neoseeker has published a review of the Sparkle Calibre P980, an overclocked GeForce 9800 GT graphics card

The Sparkle Calibre P980 9800 GT has been overclocked, thus making it better able to handle the ever-rising level performance levels of the competition -- especially one card that has just been released, the similarly-priced ATI HD 4770. As you can see from the chart below, the Sparkle has a healthy, substantial overclock. A few cards reviewed here recently have been advertised as 'overclock' yet only have a slight memory overclock, so this is nice to see Sparkle doing an overclock right.
