Doubt about Biostar 790GX 128M motherboard

[rchi84]

hi guys

i am getting a PC with the biostar 790GX 128M motherboard which has crossfire. my doubt is, will i be able to use two MSI Radeon 4770 cards on this motherboard, as they are dual slot Video Cards? Also, i am getting the Antec EA 650 SMPS. this should be enough for the crossfire right?

thanks guys

As 4 biostar mobos r known as cheap products and not good @ after sales service...' but this mobo as per review is good and can handle a hd 4770 xfire setup but do not overclock it as this may lead 2 damage in capacitors...'
