It seems as tho very very few people are running crossfire so therefore very little is talked about it other then the usual "OMFG 120FPS IN OBLIVION MAXED WITH DUEL x1900XTX!!!" I on the other hand dont have the money for duel x1900xtx cards, i recently bought a crossfire 200 mobo and have a x1600 XT which is crossfire ready, and lets face it the probability of me upgrading to another ATI card sometime in the next 6 months is very certain. ive read several articles that explain the configuration of video cards is somewhat limited. So im wondering if cards like my x1600xt work with others like the x800's series which are also crossfire ready. If anyone has any idea pls post your info here and enlighten me. Will i be forced to buy another x1600 xt for compatability? or will i needa x1900xt crossfire edition with the "Master" Multi-GPU enabling features? if i couple a x1900xt with my x1600 xt will i get any increase at all considering the x1900 is getting crippled due to the x1600 xt's 12 pipelines? this information is very hard to find, any links to articles would be apreciated... maybe a second post can be formed with all this info and data compiled and organzied to be used as a sticky for future users who may come here looking for answers.
