Got my hands on a W230SS with Maxwell. The thing overclocks like a beast. Haven't really pushed it extra hard but +135Mhz as per Kepler is possible. It also implements proper boost algorithm unlike its 650m sibling.

Maxwell inst as brute powerful as the kepler equivalent but the core is utilized much better. Thus, you will notice more consistent performance. Additionally, the beefed up internal cache makes it much less vulnerable to Memory bandwidth on models with GDDR3 though I highly recommend getting the GDDR5 variant as much as possible.

Without a doubt it is Clevo. You get unbranded hardware which means you are pretty much paying the fair market price for the hardware. The downside is that the software support tends to be very 3rd party and semi-custom.
