Just had a look at their website for these pcs and must say for an £1800 computer their choice of graphics cards verge on the ridiculous.
The card they use is actually the 9200SE which is a budget edition of the card.[not sure exactly the diff possibly slower memory]
They dont even state what All in Wonder card they are actually using on another pc.
If they have the 9800Pro in the showroom machine I would think Trading Standards or the Advertising Agency may be interested
