ATI's CrossFire solution is now a lot more attractive offering thanks to the Radeon X1900 series being released. Performance is up and above the 7800GTX when in SLI quite often and the performance increase between a single XTX and CrossFire can be seen in most applications although some greater than others.
Both of the HIS cards come with a nice package and everything you need to start tearing up those frames in all the latest games. The overall package is great with the games and huge amount of cables to make use of all the features that are on offer from the cards.
While CrossFire isn't a bad technology, the master card idea is just extremely annoying. The external connector is also a bit of a pain but is bearable. Why ATI is unable to run a setup like nVidia is beyond us. The ability to simply just go out and purchase an X1900XTX would fix up confusion amongst people who don't understand the "master card" situation and just generally make it an easier technology to understand.
HIS have done an excellent job with the X1900XTX and master card and they are one of the only brands master cards that can be found down under in Australia at the moment.
