I am currently piecing together a new system for myself. I have decided on choosing an AM2 processor and will be using ATI for the video card.

Looking at the motherboards I can see that getting motherboard with the ATI Xpress 3200 chipset will allow me to use 2 cards in Crossfire without the need of a Master card as that is built into the chipset.

If I were to use 2 X1950, I would not need to use the Y-dongle thingy to connect them at the back.

Have I got anything wrong so far?

So my question is...

Will using 2 x1950 256Mb cards in Crossfire perform better than just 1 x1950 512Mb card. In my mind I would assume it would... but by how much?

I haven't looked at specific cards yet, this is purely an academic I'm not looking at specific cards until I can get the theory down. Besides ... by the time that the AM2 Crossfire motherboards do come out in Australia... new video cards might be out.

If you really need a brand oc card... lets say

2 x SAPPHIRE ATi X1950 PRO 256meg

VS.

1 x SAPPHIRE ATi X1950XTX 512meg

If you don't already have the cards, I suggest looking at the Geforce 8 series; an 8800GTS should outperform two 1950PROs in just about everything.

I haven't bought the computer that can take those video cards yet ;) 

I usually don't look at Video Cards until I have settled on everything else. Now I have to consider Video Cards in terms of Crossfire/SLI when choosing a motherboard.

To be honest I haven't looked a nVidia. I am quite happy with ATi's support and my current card (9600XT PRO) has served me well. I haven't owned a nVidia card since my Geforce2 GTS.

I'm just curious if 2 256Mb card which are priced a little more that a 512Mb card will be a better option... or should I got the 512 route.

I think the question would still be there for nVidia cards too.

I dont think so, the 1950xtx has the old crossfire type. The 1950Pro has the new crossfire configuration.

radeon1950pro +radeon1950pro = crossfire

the radeon1950xtx + crossfire1950xtx= crossfire
