How much more RAM will 64bit Windows 7 need compared to 32bit XP?

  1. My current specs are listed, I have 2x 2gig ddr3 ram. Think ill need anymore? Or will the performance difference with more ram be minimal with windows 7?

    It depends. For regular use, 4Gb should be perfectly adequate. For image manipulation, some high-end games, the more the better.

    In general if you have experience with Vista, you will find Win7 better, faster and more efficient than Vista on the same hardware.

    Unless you run really heavy video/graphics/3d software that requires a lot of memory you should be fine with 4 Gb, you won't notice much difference if you add more.
    I have 4gb ram, and win7 is faster than Vista. Also, your 32bit XP didn't take advantage of all your memory, it's limited to a little more than 3gb.

    The actual minimum requirements for windows 7 is 1 GB, 4 GB should give you great success.

    the min required for 32 bit is 1 gig, for 64 its 2 gig, so four should be fine.

    In my opinion the more the better. Superfetch caches files to RAM, so the more RAM you have the faster frequently used applications will launch (unless your hard disk drive is somehow faster than your RAM).
