ATI's mid-range graphics cards haven't always produced the goods, but this X1900 XT is a real sensation. With performance that matches (and sometimes even surpasses) that of cards that cost an extra £30 to £40, this is an excellent deal.
Not that there's anything revolutionary about the technology: the X1900 XT isn't a brand-new card. It's simply that ATI has only just released a version with 256MB rather than 512MB of RAM.
The core and memory clock speeds are identical – although there are already a number of 512MB versions available that have been tweaked for extra performance. The 256bit memory interface is very nice considering the price tag, while you'd expect to pay £250 for 48 pixel shader processors.
In games testing, the X1900 XT destroys the likes of the GeForce 7600 GT, while not just competing with but occasionally moving ahead of the vastly more expensive GeForce 7900 GT and X1900 GT cards.
