crossfire question

[noj]

I'm thinking of going for a cross fire set up, i already have a single 6950 card (2mb version) if i want to get another 6950 card does it have to be from the same brand or will any 2mb 6950 work?

I currently have an 850w PSU, do you think that will be man enough or do i need something even bigger?

sry just noticed i posted in the wrong forum area...apologies!

Any 6950 will work, it can even even be the 1Gb version. As long as the GPU family is the same,

Is it a good make? will be fine if it is.

its a bequiet modular PSU, about 2 years old so hopefully good enough

It is.

Card specs for sli or xfire
850 more than enough and if branded will have the 12 amp rails for it
good luck and post pics?

Although the 1Gb will work, it will limit performance in some games, noticeably BF3, it can make the difference between custom settings and everything on Ultra.

6950>70 CrossFire on a 750w SeasonicX modular here, so you should be fine with your Bequite.
