    Vista 64 bit will access up to 128GB of RAM depending on which version you purchased. I assume Windows 7 will have similar limitations. http://msdn.microsoft.com/en-us/library/aa366778(VS.85).aspx

    The reason for either 3GB, 6GB, or 12Gb etc. of RAM is because the i7 uses a triple channel RAM controller. DDR dual channel required 2 DIMMS for optimal performance. Same principal just a hell of a lot faster.

    As far as how much RAM you should use I would go with 6GB. 3GB isn't enough these days and 12GB is still too much for 99% of us.

    For the gfx card I would suggest these instead of the 280 depending on your budget.

    FYI the 4890 will perform closer to the 285 than the 275 will which is why I suggested it. The only exception to that is Crysis where the 4890 will most likely lag behind both.

    I was bored when I got to the forum this afternoon so I went ahead and built you an i7 system on Newegg. All the choices I made were based on what you asked for, quality, and reasonable pricing. I got a grand total just over $1400. Do with it as you see fit. Sorry for the tiny text I didn't feel like doing anything fancy so I cropped the pic and resized it using Paint.

    Is there a reason why you have a 4870 selected to buy instead of a 4890?

    Go for a 4870 x2 instead of the 4870 if your not going to get a 4890. Save a few bucks and wait for the 5800 series, unless your heading to nvidia.

    I haven't had any problems with games being incompatible with 64-bit.

    GTA: San Andreas
    GTA 4
    Saints Row 2
    Call of Duty 2
    Call of Duty 4
    Combat Arms
    Arma 2
    Second Life
    JFK Reloaded
    Crysis
    Spore
    Godfather II
    Battlefield 2
    rFactor
    Ghost Recon 2
    America's Army

    i have read call of duty 2 isnt compatible with 64-bit, but it works just fine.

    64-bit will address a hell of a lot more than 128GB.

    If you are a gamer then go for 6GB. If you are a Ultimate gamer :biggun: who must have the best PC ever then get 12GB

    Only way he could even do that if he used 4x2gb DDR3 sticks which would kick the board into DS mode from tri memory mode. But on a I7 platform the kits come in 3x#, 3x2gb or 6x1gb is enough.

    Totally dependant on which motherboard you have.
