    0rdered corsair 1200 should do the trick

    i picked up the cards from here

    http://www.scan.co.uk/products/6gb-x...k-dvi-i-mdp-pl

    they are priced here for 371 uk pounds (for soem reason i cant use pound sign it shows as a question mark lol) and i had a discount code also so worked out at 350 each

    hopefully they will be ok coz 1 thing i HATE XFX gfx cards in my experience they are poorly made and have crap chips...

    but at that price i thought i d chance it :o

    The other big question is whether you have enough separation between PCI-E slots for two 7990's and space between the last PCI-E slot and anything else.
