Thats the thing i wanna know from anyone if this has been done before cause it is quite a bit of money to play guessing games with....
Correct, it is impossible. x1950 cards use DDR4, x1900 cards use DDR3. It's not like a pipeline number/GPU clock/memory speed issue issue in which one card is able to disable pipelines or cripple the clock speeds in order to work with the other. The chipsets are the same but it simply won't work. You need an x1950 crossfire master card to work with an x1950 slave card. For now just one x1950 should do you fine, power-wise. Wait for the price of the crossfire card to drop and get it later, when it'll cost you less but still give you a nice boost. You may also have other options by then as DX10 cards will be arriving in e-stores and you know how ATi and nVidia like to keep chucking out rehashes of old cards.

Well I have Asus X1900xtx graphics card and looking to add another prized possesion to my PC but i was wondering if I could install a x1950 crossfire instead of X1900 crossfire card?

What I gathered from that article is that ATI is doing away with the Master/slave cards in Crossfire and now that any brand of X1950 Pro can be used with any other brand of X1950Pro i.e. MSI + Asus

What bugs me is that I bought the 1900XT for $500 (a bargain at the time) and now because of scarcity the 1900 Crossfire is still over $500, whereas the 1900XT and XTX can be had for less than $300. And I can't use the 1950 Pro which is much cheaper than the 1900 Crossfire. If I had bought a crossfire Master to begin with, then adding a slave would have been much cheaper later on.

First you say they can go crossfire and then you say different chip designs can´t. The 1950 Pro is a RV 570 while the 1900XTX is a RV580. So the OPs proposal shouldn´t work, right?The reason that that's the case is because they have the dual internal connector on every card;
So it's not BUS Xfire like the GTs and GTOs but still hardware support, but now each card has that ability.
Also it has nothing really to do with the OP's question, but it's the right way to go with hardware connected Xfire IMO.
As for the OP's question, the X1950 cards do work with the X1900 cards in Xfire, check out DH's review;

Still a little quirky overall as is the entire Xfire/SLi solution.
Seriously guys stop giving people advice based on your guesses, you cost people time and money and just look st00pid!
The first thing to remember is that Xfire doesn't have the same limitations as SLi, unbalanced cards is built into the setup, what you can't do however is match completely different chips designs (like the X1800 with an X1900 or X1600 card). Dont' think speeds or pipes (both can be off) think architecture.
And whomever said GDDR4 mattered needs to rethink that statement, it's abot as wise as saying you can't put a sapphire card in your rig because it's blue not red. :roll:
To the OP, I'm not a fan of XFire or SLi, and would suggest waiting for newer cards to come out, but if you got money to burn (which later comments seem to say you don't) then Xfire will show a boost, just not a huge one.
