    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.

    You can only crossfire with another x1600 pro/XT, if you buy a pro your XT card will work like a pro, including pipelines, get another x1600xt in my opinion

    so one must use identical video cards? exactly like SLI? exactly like ATI said it wouldnt be like?

    The original concept was so that the average consumer who upgrades his video card every 6 month or so wouldnt be forced to throw the older card away... that he would still be able to get an extra push by combining them.

    so how do duel x1600XTs compair to a single greater card like the x1900xt?

    well lets think about it. X1900XTX is clocked about 650/775, with 16 pipes and 48 vertex pipes, correct? A single X1600XT is clocked about 600/700, with 12 pipes and 12 vertex shaders. So dual X1600XT would have the effect of a card clocked at 600/700 with 24 pipes and 24 vertex shaders, if I understand SLI/Crossfire correctly. Oh yeah and the X1300/X1600 series is special, no need for a "crossfire master edition" of the X1300/X1600.

    You will alway have to use the same series card so if you have a 1600 you can use any 1600 card for the second card.Once you hit the 1800 and 1900 cards you need a master card on your mobo ,but the new crossfire mob will let you use any 1800 or 1900 card no master needed but the rdx200 needs to have a master card in the 1800 or 1900 series as where the 1600 you dont need a master card just another card in the same series.

    So, if i buy another x1600 xt, i can get close to the performance of a x1900 series?

    i see them refurb on newegg all time for like $130. If its true about the performance i will be damned happy. as i bought my HIS x1600 xt retail for $170. i know duel x1600xt would outperform a x1800 card, and if i get the second x1600xt for about $130-150 i would have paid less and gotten more.

    And yes i do see the only downside is next time i want to upgrade i have to ditch both and buy a $400 single card to see a boost in performance.

    No your performance will be closer to the x1800xt not the x1900xt , srry.

    So would it be better to buy another x1600xt for $130 and get x1800xt performance, or buy a x1900xt and then next time i upgrade ill just get another when the prices are down.

    having great performance for cheap, which means the next upgrad will be crazy expensive.
    or have it be expensive now but perform better then whatever single card will come out within the next year.

    i guess it doesnt matter, im still paying more for better performance, just in alternate intervals.

    actually now that i think about it, im not impressed with this video card at all. I am definetly going to wait a few months and buy a top of the series card. every single series i buy i always get the mid ranged because i never had an income.

    before this x1600xt, i had the x600pro, and before that i had the 9550. never had a top of the family, or flagship card. I really am sick of buying the second rate.

    DX10 is coming out soon right? so ATI will have a new line of cards for that.

    Also Ati is supposedly going to integrate a physix aperature to their cards correct? i guess i will get the flag ship of whatever the next major series is.

    Lol...I must say it is sad for people to answer who have little clue about SLI and Crossfire. Please do not listen to DRDNA when he says it will be close to an X1800XT. He is misleading you.

    There was a nice article of Crossfire and SLI and how they worked here on techpowerup.com. I am too tired to search for it, but it is around here somewhere. The idea is to try to extend the life on older cards. I used to want to do SLI/Crossfire, but was turned off when I found out the truth on it. When the cards are SLIed/Crossfired, there is only (at max) a 10-15 percent increase. That rarely happens. In most games there is only a 5-10 percent increase in performance. Thats why it is always better to shell out more money for one great card, then just 2 mediocre cards. In my opinion SLI/Crossfire is only worth it if you can afford the 2 best cards on the market. Then I can understand that, but for a low/mid range card, SLI/Crossfire is not worth it. So save up for an X1800XT (they are coming down very nicely in price).

    Oh yea and DX10 cards will not be out until 2007. So ATI and Nvidia will release more cards until then.

    Just exactly what advise did I give wrong to our friend in need of advised????? I would not and did not advise him to buy another mid range graphic card!!!!!! By the way I myself have x1800xt and a x1800 master running in crossfire and a second system with two 1600xt's and I will tell you right now that the x1600 crossfire runs aLmost the same as one x1800xt .....and I have two crossfire systems!!!!! Come on get it together!

    lol who cares what you do....Listen take a look at the interactive GPU list over at Tomshardware or whereever you want to. SLI/Crossfire isnt worth it unless you get the high end GPUs. The price of 2 x1600xt's are more than 1 x1800xt and the 2 x1600xt's dont do horrible, but not that close to the x1800xt. The problem is that there is always OverHead when you switch between GPUs. So dude dont get mad....LOOK AT THE FACTS..
