    I was looking at the m11x r3 and was just wondering the performance difference in the base CPU of the r3 to the U7300 in the r1, also is upgrading to the i5 a good performance leap?
    Many thanks for a decent answer.

    umm the r3s dont come with a i3 processor, only the 700 dollar r2's on the alienware site now. but the performance difference of the i cores is vastly superior to the C2D in the r1.

    so little perf gain on the i3 its pointless IMO. However the graphics switching is diff on those models and maybe some will prefer that.

    i5 should kill it on perf and there are threads here on the i5 and improving it further if not already better.

    Had a guy do a CPU wPrime test on an M11xR2 i3-330UM ages ago and it did perform marginally better than an OC'd M11xR1 SU7300 1.6Ghz.

    Think it was something like:

    SU7300: 53sec
    i3-330UM: 48sec (where lower is better)

    Compare SU4100, SU7300 and i3-330UM

    Just get the advantage of 4 threads on 2 core, where the SU7300 only has 2 threads on two cores.

    No turbo boost on i3-330UM.

    I'd go i3-330UM myself, for ease of nVidia updates, at maybe the loss of a bit of battery life.

    If I had to choose between the two.

    Thanks for the great reply DrGoodvibes.

    deadboy90, that may be what you think, but I am from the UK and over here it comes with a i3, i5 or i7. Also upgrading to the i7 gives you a 1GB video memory boost

    yes but its not an r3, the r3's use sandy bridge and the 540m, the r2 use the first gen i cores and 335m, look at the tech specs on the ordering page: i3 330UM and 335m. meaning its an r2

    The Intel(R) Core i3 2357M is sandy bridge deadboy.

    That is an R3 for the UK it comes with the 540m.

    I would get the i5 personally because it comes with the turbo boost which is considerable.

    Do not get the core 2 duo unless money is an issue.
