网上看到一款二手的 HP-Zbook-17-G2-Workstation-i7-4940MX-3-1GHz-32GB-Ram-DreamColor HP-Zbook-17笔记本
配置如下：
-- Intel core i7 4940MX 3.1GHz Quad , able to go up to speeds of 4.0GHz --
-- 17.3 LED IPS DreamColor Screen with 1920 x 1080 Resolution --
-- 256GB SSD & 500GB HD (Open 2.5 Slot) --
-- 32GB Ram --
-- DVD Burner / Player ( Can play and burn blu-rays, but buyer will need software) --

主要看上了17.3 LED IPS DreamColor Screen&Intel core i7 4940MX 3.1GHz Quad （视频&图片编辑、渲染爽啊）&全尺寸显卡（可以ADIY）请教问题如下：
1、HP-Zbook-17-G2可以上P5000类的显卡吗？
2、到手8000多元值不值？
3、G2工作站散热如何？
