    Weird discrepancy

    So I looked at Intel's pages for the two lower CPUs offered for the m14x:

    Intel® Core? i7-2630QM Processor (6M Cache, 2.00 GHz)with SPEC Code(s)SR02Y

    Intel® Core? i7-2720QM Processor (6M Cache, 2.20 GHz)with SPEC Code(s)SR00W, SR014

    and the first one, under, "Memory Types," says "DDR3-1066/1333" while the better one says "DDR3-1066/1333/1600".

    All of the memory that comes with the m14x is 1600, so is Intel's page wrong?

    (Another weird thing is that Alienware's website shows the normal clock speed for the i5 in the m11x, but it shows the turbo speed for the i7 in the m11x. The m14x's page shows both normal and turbo speed.)

    It's just weird, I guess.

    no, intel not doing wrong..

    2630 only support 1066/1333, so if you choosing that 2630 your ram performance will underclocked to 1333

    You can set your RAM in the BIOS to 1600, however...so no worries.

    That makes me want to get the middle CPU just to be safe. Do you think it increases performance significantly (the 1600 over the 1333, and the increased Ghz)?

    Memory speed has a very little performance gain. Its better to get more slower ram than less faster.

    What about the CPU gain?

    For gaming, the gpu will be the bottleneck, so its pointless to get a faster cpu unless you do video encoding or something. I have a i7 2600k at 4.5ghz with a gtx 580 and I don't gain any frames going any higher unless I overclock the video card.

    So there's no reason to get a better CPU than the base one. Is that the consensus on these forums?

    based on the specifications/opinions, the answer is yes
    why? because the limitations of the graphic card, a faster processor would only create a bottleneck
