Do I have enough power for crossfire-goodness?

[Hussman]

Hi,

I'm hoping to run an ATi x1900xt mastercard with a Sapphire x1900xt-x slave.

My power supply is a Hiper 580W lump.

Will I be able to do it, or will I need a mini-nuclear reactor to power these beasts?

Thanks

PS : Rest of my PC is in my sig, on the right.

Thanks for all the input.

I already have a type r and don't really want to buy another PSU.

Looks like I should be ok then?

Thanks again.

Hi,

Can you please clarify, will it throttle back to XT speeds, or will it run at xt-x speeds?

I've heard many, often conflicting, reports about this.

Thanks

Great, so basically an x1900xt mastercard and an x1900xt-x slave will be better than an x1900xt mastercard and an x1900xt slave?

So if I ran them at stock (no overclocking) would I see any "real world" difference?

What about a "guestimate" at the increase in 3dmark 06?

Thanks in advance.

So do you recommend me saving the £30 and getting the XT slave card and putting the saving towards the new Zalman vf900 cooler?

Thanks for taking time to explain it all.

Cheers everyone!
