电脑装机市场鱼龙混杂，小白消费者极易掉入装机骗局。临近双.11促销，电商平台上无良商家蠢蠢欲动，以“低价高性能”的幌子设下骗局。
萌新小白无辜，何苦骗之？
探访电商平台，发现不少商家宣传的主机配置“猫腻多多”。典型配置为：GTX 1060 3G显卡 搭配号称“i9级别”的CPU，起初令人心动。但定睛一看，“i9级别”处理器竟为E5-2660，瞬间索然无味。
无良商家配置单含糊其辞，硬件描述不清，显卡、内存等品牌参数深藏不露。正规电商的产品配置单绝不会如此遮遮掩掩。

E5-2660是英特尔十年前的旧款服务器级至强处理器，如今被不法商家利用为坑害消费者的“利器”。
E5-2660
E5-2660虽然核心线程较多，但CPU频率极低，仅为2.20Hz，日常办公还算凑合，但实际应用性能堪忧，尤其不适用于游戏。这种老款处理器并不值钱，却在奸商的炒作下身价暴涨，成为了欺骗新手的工具。
避坑电商主机要点之一：切勿轻信“媲美”“i9级别”的至强处理器，极有可能是骗局。
仅仅“i9级别”这一处猫腻还不够，为了让大家更直观地感受这种“性能强劲”电商主机的实际威力，笔者已购买一台并收到货。
无脑坑
老实说，收到主机后，笔者也被其外观所迷惑，精致小巧。然而打开机箱后，里面的硬件顿时让笔者大跌眼镜。
除了山寨，还是山寨。
电源：山寨
寨了
散热：山寨
寨一
内存：成本只剩下山寨了
寨二
固态：寨就对了
寨三
主板：还是山寨吧
寨四
机箱：凑齐“i9级”
寨五
emm，除了“i9级”老至强不是二手就是山寨，这样的主机，稳定性和性能堪忧。
避坑电商主机要点之二：不要相信低价电商平台质量，二手山寨聚集地。
有朋友应该发现了，笔者还没提起显卡，难道卖家良心发现了？显卡幸免于难？可惜，事与愿违，显卡的问题其实更严重，因为这不仅是二手，还是一块矿卡！
Beware
The graphics card's PCI connectors show signs of heavy usage, with discoloration and darkening.

The key to determining whether this is a used or mining card lies in its video ports.
Spotless Video Ports
If this were a used card, its video ports would be far from pristine. Only mining cards, which don't require monitor connections, exhibit such clean ports. This is a useful tip to distinguish between used and mining cards. The seller's blatant honesty is commendable.
Beware of E-commerce PCs Featuring Low-Priced GTX 1060-Level Graphics Cards, As They Are Likely Mining Castoffs.
Let's test the performance of this e-commerce PC and compare it to a genuine build we assembled using parts from京东.
Recommended Configuration
We used Colorful's latest Colorful GeForce GTX 1660 SUPER 6G graphics card, along with a 6-core, 6-thread Core i5 9400F CPU, and Colorful CVN B365M GAMING PRO V20 motherboard. Purchasing these components as a bundle will result in significant cost savings compared to the shady, used host vendors.
Colorful CVN B365M GAMING PRO V20
Let's compare the CPUs of our two builds.
Super PI:
Super PI
When gaming, what matters is the processor's single-core performance. Super PI, a program that calculates pi, provides a good measure of a processor's single-core capability since lower values indicate stronger single-core performance. There's a noticeable difference in performance between the i5-9400F and E5-2660, highlighting one of the drawbacks of using shady, used PCs.
Cinebench R20:
Cinebench R20
Cinebench R20 is an industry-standard CPU benchmark software used by most mainstream media outlets for system performance testing. Again, the i5-9400F and E5-2660 show a significant gap in single-thread scores. The biggest problem with these outdated E3/E5 platforms is their low clock speeds, which compromise gaming performance.
Game Testing:
Finally, we have our game performance test using Far Cry 5, PlayerUnknown's Battlegrounds, and CS:GO. Graphics settings were set to the highest preset, with resolutions of 2K and 1080p.

《CS：GO》和《绝地求生：大逃杀》游戏测试中，搭载七彩虹战斧 GeForce GTX 1660 SUPER 6G显卡的DIY主机表现明显优于二道贩子组装的非正规电脑，帧数差距显著。这说明非正规电脑的性能存在不足之处，且价格并无明显优势。反观正规渠道组装的电脑，不仅性能稳定，且提供可靠的售后保障。购买电脑时应选择正规电商渠道
总结：
强调正规电商渠道购买电脑的重要性。原因如下：
- 优质售后保证：二道贩子无法提供的保障。
- 商品质量保证：正规渠道的产品更稳定。
- 性价比：长期使用正规渠道购买的电脑更划算。
综合考虑，在相同价格范围内，选择正规渠道购买电脑才是明智之举。
