4890's in crossfire or single 5850?

you know what, i kinda just had a little think about this!!

my psu is a coolermaster 700watt with one single dedicated 12volt rail pushing 50amps, i dont think my psu has enough guts to push 2 4890's never mind connections

the cards require a 6pin and 8pin pci-e power molex and my psu comes with 2 8pins (but has 2 pins detachable to use for 6pin)

so i would have to buy a decnt psu-£140+

i think 5850 is on order now, cancel the 4890!!!
