I need a 15" screen laptop, which is not too heavy, and yet has a good graphics card. I had read on various American forums that the MSI GT 628 was the laptop to get. But it did not seem to be available in the UK. OC and their competitors here in the UK all sell the MSI GT 627, but not the more powerfull 628. Now however MSI uk's website lists the GT 640 as their most powerful 15" machine, with an even better graphics card than the 628. So questions are; a) Any idea when the 640 will be on sale by OC? b) How heavy is the power supply (the laptop is quoted as weighing 2.7kg)? c) how much will a 640 cost?
