Which card?

[adzx]

I need to choose between these two cards for a crossfirex or sli setup.

and

I'll be running three screens, one is 1920x1080 and the other two are 1280x1024.
Also what're the overclocking capabilities of these cards?

The 6950 is the better of the 2 but getting a single 7xxx series card would be better than 2 of the ones you linked, I am not sure buy I don't think running monitors of different resolutions works as well as when there the same. Also for 3 screens a 2Gb card is better. How about this http://www.pixmania.co.uk/uk/uk/11675485/art/sapphire-technology/radeon-hd-7950-3-gb-gddr5.html

Well, I won't be able to purchase a pair of either of the above cards at the same time, I'm not going for a 7xxx because I wouldn't be able to purchase it straight away, I'm going for a sli/crossfire because I won't have all the money at the same time
Also, do you mean dual cards aren't good for diff resolution monitors?
