Hello, I bought the Shenzhou K590s I7D2. It seems that there is no D2 now. The performance is absolutely OK. I use my own bios and then install Windows 8 (if not,Windows 8 will be silent). The boot time is less than 18 seconds (the time given by 360 security guards). The bottleneck of this laptop should be the hard disk. My laptop does not have a solid state disk. The laptop may be a bit stuck when it just starts up. It should be installed with a lot of software for me. They all start up before the boot. It will take about 2 minutes. Other times are very good.When playing the game, the fan is very quiet (it proves that the heat dissipation is strong). After the game exits, it is very quiet.I think the quality is average, but I have bought my laptop for three months. Every problem, if you buy it, I can teach you to install Windows 8.Pure manual typing, hope reward.
