sapphire HD 2900xt, pci-e, 512mb in crossfire mode

Hi there.I have just ordered a ''sapphire HD 2900xt, pci-e, 512mb'' and was wondering what kind of crossfire setup is needed for this card, I know that with my old X1900xtx I had to have one crossfire ready card and another crossfire edition card for crossfire, is it the same with the HD 2900xt cards or does it simply need 2 identical cards for a crossfire setup.And also would a 750watt power supply be enough or should I get a larger power supply for this.Many thanks.sapphire HD 2900xt, pci-e, 512mb in crossfire mode
750W PSU is fine. If you're using newegg, just look for a 'Crossifre Ready' motherboard, or do you already have one?sapphire HD 2900xt, pci-e, 512mb in crossfire mode
I think it's spelled: ''Leonidus'' or something...

lol I wasnt sure about the spelling there :)I already have the motherboard which is crossfire ready, I just am not 100% sure about what configuration the cards will need, like one card being corssfire ready and the other one being crossfire edition.
Crap, didn't know that mattered...I'm not sure then...

I have two HD 2900XT's but you NEED a crossfire motherboard there are some good ASUS ones on newegg I have the 580x and it owns
basicly to run crossfire it is very simple now with the hd series.you need 2 identicle cards so say 2x hd2900xt 512mb ( idont know if it will take one 512mb and one 1024mb one)the cards come with the adapters which go on top of the cards in the case to link them together, so as everyone else said all you need then is a crossfire motherboard and your away!
As most of what other people said, CrossFire has become a lot more simplified. You simply need two identical cards (you don't need a master or a slave), and connect the two together with the CrossFire bridges.Also, what 750w PSU do you have? Depends on the company/OEM who built the PSU.
oh yea im 99% sure the 1gb and 512mb wont work together because the 1gb is GDDR4 and the 512mb is GDDR3 im pretty sure mixing ram types will cause future problems.

natural instinct
