An excellent peice. HP NX 6125 is equipped with an AMD T64 ranging from 1.6 GHz to 2.0 GHz and is complimented by an ATI x200 chipset (x300 video processor IGP) which currently is the best IGP solution available ( the only drag is its shared mempory 32-128MB). the processor is a 35 watts monster which requires the fan to be running at all times. The laptop displays no heating problem as such unless you load the processor and the graphics core with some fancy game The processor is 64 bit enabled which means its built for the future plus the x300 Video processor has HW T&L ( something intel cards dont have and rely on the DirectX SW support for them) and a shader model 2.0 This includes vertex shader 2.0 (something again the intel GMA does not have and relies on DirectX SW support) and a Pixel shader 2.0 ( something the intel card has but is poorly implemented)
