The core i5 is a ULV part and it's dual core. Not quad core. Comparatively speaking it is a little bit "dinky" versus desktop parts.
I run a Mac Mini with a quad core i7 and 16GB of RAM. Beyond that consideration, desktop parts are almost always under less thermal stress then those on a laptop and can typically run at higher clocks.
