At the time of testing the most recent drivers we had were the Catalyst 5.12 drivers but when we finished testing we got a hold of the soon to be released 5.13 drivers which have shown us quite a performance increase for the X850XT card. While we haven't tested the new drivers on the X1800XT, we would assume with very little doubt that we will get a nice healthy increase in all the programs much like the X850XT got it.
The GeCube card as always is a pleasure to use; it overclocks easily, comes with a nice bundle and offers a very competitive price. We have also heard that GeCube are releasing an "Extreme" version of the card which we'll try to get into our labs soon and test.
GeCube have got a nice card here and some people are going to prefer to go down the ATI route as they may feel more comfortable with driver support and just the general support that ATI offer over each month. If you would upgrade from an X850XT to the X1800XT only you can decide and depending on what games you play will help make the decision easier.
In the New Year we hope to see the extreme version of the X1800XT from GeCube.
Nice upgrade from the X850XT overall
Great X1K features
New full version game
Competitive GeCube pricing
New drivers give us a healthy increase
Still not as fast as the 512MB 7800GTX
