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.
