技嘉 P25X v2 笔记本电脑简短评测

Name: Gigabyte P25X v2
Brand: Gigabyte

个性演员。 尽管大部分笔记本生产商都在它们的15寸产品中使用GeForce GTX 870M，技嘉却独树一帜地为P25X v2配备了Nvidia的顶级显卡。同时其他的功能（蓝光刻录机、mSATA固态硬盘等）也显示了它的高端定位。请阅读我们的评测以了解这款笔记本是否真的值2000欧元（约15860人民币）的价码。

一款为个性用户设计的高端笔记本电脑。或者类似的广告语会很适合P25X v2。视觉上它给人一种独一无二的感觉。而在公共场合打开一款亮黄色外壳的笔记本也确实需要一些勇气。

不过，技嘉为选择这款笔记本的用户提供了高性能，和出色的屏幕。稳定的可视角度范围，绚丽的色彩和高对比度：可以说是一块理想的屏幕。体验到了IPS屏幕的优势的用户都不太愿意退回TN技术屏幕的时代了。

超快的GeForce GTX 880M和RAID固态硬盘的组合，让使用Windows操作系统变得更加流畅、享受。令人吃惊的还有它机身的尺寸并没有因为强大的硬件而变大。P25X v2可以很方便的随身携带。另外的优点还有它的键盘背光功能、好用的触控板和超长电池续航。

我们最后提到的一些优点可以在一定程度上弥补它在工艺质量上的缺陷。对于一款售价2000欧元（约15860人民币）的产品，大家当然会期待它有更高的机身质量（实际上它的部件结合不够紧密，键盘制造粗糙，屏幕上盖也不稳固，等等）。噪音的问题也让这款15寸笔记本没能获得更好的成绩，相比之下竞争者们的表现比它好出很多。总体上，技嘉P25X v2是一款优秀，但不算出色的笔记本电脑。
