    Good evening,

    I have researching for a few months now about looking into either a Radeon 6970 or using 2 6870 in Crossfire. I currently have a MSI Twin Froz 2 6870 already OC 930mhz. I have in mind of getting another MSI twin froz 3 already OC to 930Mhz. My questions and concerns are the following.

    1. I currently have a 750 watt PSU will I need upgrade to a 850 watt for stability?
    2. Will these two cards enable better performance to run games like RAGE, CRYSIS, SKYRIM on possibly max settings?
    3. My mother board has 2 PCI EXPRESS SLOTS for Crossfire but downgrades to 8x8x config instead of 16x16x will the performance suffer or should I get a 6970 high end card?

    Any Further advise would be great please let me know whenever possible.

    Thank you,

    May as well wait for the HD7970 and grab one of those instead.
