    At this point in time, most of the issues are related to poor driver support. Expect this to end soonas nVidia updates their driver database and new revisions come out.

    Also what specs does your comp have? maybe the 7950's had lame rigs.

    3DMark06 isn't a very realistic representation of gaming performance. In any case, you're going to be severely CPU-limited with those, so don't expect them to be a whole lot better.

    The 7950s are basically two 7900 GTs in SLI, so yes..it will be quite a bit slower than two 7900 GTXs. Granted, 4(two 7950s) has more computing power, but will also have twice the overhead.
    Quad SLI is only a few months old...are you sure your motherboard supports quad SLI? Can you see 4 separate lines when you have the "show load balance" turned on?

    And, as stated above, you will see a healthy performance improvement with a CPU overclock.

    For a healthy boost he needs 3.2GHz+ or a Conroe/Merom/Yonah. Plus the drivers are just not working well with those cards at all yet. Getting one of those for a non-SLI motherboard is a good idea. Using them in SLI is going to take an extremely fast CPU to be able to push them. I have heard drivers will be out in the next few months to properly enable them in SLI,

    It does not matter how much it cost, it matters how much data it can transfer to the cards. If you had normal SLI, your CPU is just about fast enough to run 2 normal cards in SLI. Running Quad SLI is something that no PC out right now can do. Conroe looks to be the only CPU that has the power to push them and the next AMD CPU the K8L withthe 65nm process should also be able to push them, but it won't be out until atleast the end of the year.

    Thank you so its going to be hard for me to beat my old 7900gtx scores and do u think i made a mistake buying these cards.

    Yes and no. In my opinion, your best bet would be to sell one and enjoy your PC as it would play any game out and anything to come for at least the next 2 years. You could wait and see if better driver support helps, but unfortunately, no 90nm CPU can push enough data to them to make it worth the trouble. It is like using a 3000+ Venice for 7800GTX SLI. It just can't get enough to the cards to see the results. Plus, the major makers are getting newer cards ready for market within the next year for DX10 and Vista. If you can afford to keep them and wait for the new AMD K8L CPU's due out before next spring, then by all means I am the last person to talk someone out of keeping dual cards. Either way, when Vista and DX10 take over, support for DX9 cards will slow down and in about 3 years you will need a DX10 card to get the most out of games.

    What do you run for a monitor? If you run crazy resolutions, then you could actually see some benfits of those cards. I personally run a 21" CRT @ 1600X1200 with everything completely maxxed with detail and AA/AF levels that single cards cannot run. If you run any lower resolution/settings you will never see the true benefits of those cards.
