Crossfire HD7770 or Single HD7850?

Hi, All
Needing suggestion on whether a Crossfire HD7770 OC edition or a single HD7850 would be better?

HD7770 - http://www.pbtech.co.nz/index.php?z=p&p=VGASAP7772&name=Sapphire-HD7770GHZ-OC-EDITION-1G-GDDR5-PCI-E-3.0-V ($252)

HD7850 - http://www.pbtech.co.nz/index.php?z=p&p=VGASAP7850&name=Sapphire-HD7850-GHZ-EDITION-2G-GDDR5-PCI-E-3.0-Vid ($390)

Mobo (ASRock Z77 Extreme4) - http://www.impc.co.nz/products/al_z77-extreme4.html
(dual x8 pci.e crossfire)

it will be 110$ more expensive with 2xHd7770 OC edition
But i won't plan on buying both at the same time ~
I would save $130 from getting the 7770OC then the 7850.
but would crossfire the 7770 soon (don't want to completely empty out on wallet :D )

Thanks~

  1. Dude... That's really expensive

    Get the 7850 :).
  2. 2x hd7770 is better 1X hd7770 is actually quite good but 2 is very good as they scale at
    90%+
  3. thing is if you go for a crossfire, you will get more heat issues not that you get overheating but expect making a good airflow
  4. go for the crossfire 7770's

    the fps difference between a 7770 at 1200 core 1400 mem is 5 fps compared to reference clocks. So, with that, you can get nice 1100-1150 core and a 1300-1350 mem clocks with the card i linked, you will be only missing out on a few fps, but save money and get the best bang for the buck at that price point.
