Earlier this year we were sent our first
9800 Pro based card, it was a 128mb card and at the time thoroughly
beat every card on the market in games, benchmarks and Image Quality.
As the months moved on the 256mb variants were released to give the
range that extra speed to convincingly outscore the Geforce FX 5900
Ultra. As with all technology things have continued to move on at an
astounding rate and today we have the opportunity to tell you about
ATI’s latest card, the ATI RADEON 9800 XT 256mb.
