I love the 767 for its long haul capability. The 767 is pretty hard on the frame rates in FSX, but depending on what your 3.2 GHz CPU is, your computer could handle it. If it's an i5, i7 or one of the latest AMD, then you should do fine with it.

If you are into shorter flights, then I think that the 737 is probably better suited to you. Especially around Hawaii. The only problem is that at the moment it doesn't have the VC and Cabin, so you don't really know how it will be until the Base Pack is released.
