7950 Crossfire question

[Nuclear Fusion]

I'm soon (in about an hour or so) to be the owner of a 7950 TF3. If in the future I wanted to go down the crossfire route, I was wondering whether 7950 CF presented any kind of problems I should be aware of, such as the dreaded microstutter. Also, would my current PSU (rig in signature below) be sufficient?

I don't think your PSU will cope unfortunately.

Anyone out there with a 7950 CF setup that can advise me with regards to microstutter and driver issues?

I have had no problems at all, really happy.

Think you need a beefier PSU though.

 

[Nuclear Fusion]

Ahh ok thanks, so I probably would need a new PSU which isn't ideal, but at least there shouldn't be any problems. I seem to recall that micro-stutter was mainly only a problem with lower end cards in crossfire anyway.

What would you guys recommend then, 750W?

 

[RichH]

If you are not going to overclock 750 would probably be ok.

I'd play safe and get at least 850W if i were you - that is what i did anyway.

Not sure what the power consumption of the 7950's are like but my 680 SLI set up with overclocks on everything is fine with 750W. I have headroom as well.

 

[RichH]

How do you know you have headroom?

I only got microstutter in BF3 but it was solved with 2 lines of a user.cfg file. Really smooth now
