    Hello
    Just wondering if there are any major issues with xfire on my Asrock pro 4 mobo with 2 sapphire vapor x 7950's
    I've heard mention of there being space issues and I know it's only got 1 x PCIe 3.0 x16 Slot so it might bottleneck the card but I will be getting a new mobo further down the line..
    Not to be cheeky but I'm ready to pull the trigger on the 7950 so my Sister can bring it home from the states at the month..for the grand total of €205:)

    You will lose about 10-15% I think. It depends on the card and clocks. It will still give a big boost to performance.

    You would want a decent 600-700w minimum psu to run those though.

    I'd say 700w to run them efficiently. You want to keep the psu under 60% of it's capacity or so.

    I've got a 680w

    Do you reckon that's enough?
    As I said I'll be upgrading the mobo later on

    Thanks for that..... Read through it didn't understand much until the conclusion. :o
    I'll be ok with the pro 4 and I knew the psu was enough I just needed your learned selfs to reassure me.
    Thanks Lads. Hugs?:pac:
