    How much are you looking to spend, what games/apps are you expecting to use (and at what settings), are you willing to upgrade your cpu and what are the other intended specifications of the system?

    Looks like it's down to which mobo you want. X38/X48 don't do SLI...

    3870x2 + 3870 is going to be faster than 2 9800gtx's in SLI.

    It really depends on what your price range is, at this point in the game 9600gt's perform extremely well, but if you're on the highend its a different story.

    I am intending to run the following components

    Intel Core2Duo E6750 (would change when new ones are launched)
    DDR3 1600MHz
    and the graphics is down to the mobo i choose.

    You'll save yourself money by going with an X38 motherboard and X-fire with comparable performance versus 3GTXs on a 780i board. For example, a Gigabyte X38 with Sapphire 3870X2 and a Sapphire 3870 will run you roughly $850 after parts are shipped, an eVga 780i board with 3X8800GTXs will run you roughly $1500 with comparable performance to the HD3870's.

    Edit: That E6750 should OC fairly well, I recommend ( if you weren't going to already) installing a good after market cooler such as a Thermalright Ultra or a Zalman 9700. I'd expect an OC of around 3.6+Ghz depending on the chip. Also, you could save yourself some money and go with some DDR2 800 or 1066mhz ram. Maybe add a couple of GBs as well?

    I have seen somewhere i cant remember that the 3870's dont do well when AA is enabled, and come behind a 9600 GT. but i am not aiming to go tri sli with 8800 GTX's may be 8800 GTs would do the job. what i choose, i am really sitting on the fence here.

    Get a X38, HD 3870X2 and a HD 3870. My HD 3850 only loses around 4-10fps with 2x AA but I dont really use it that much.

    Two 8800GT(s) in SLI are great on a 780i board. But I'd just as readily say go with a 3870X2 on a x38 board with the option to add another 3870X2 or a 3870 in the future. Both are priced and will perform similarly.

    Edit: Again, if we know your specific budget it really helps.

    9600gt's are very powerful, but they're not better than 3870's. Although you are correct about the whole ati cards suffering with aa+af and such, they do seem to take a bigger hit.

    Also take into consideration that a single 3870 is usually identical in price to a single 9600GT. There are advantages/disadvantages to each. 9600GTs tend to run quieter and draw a little less power than 3870s.
