不同的升级方法都能不同程度地提高PC的性能,但对于那些较老的PC来说,最好的升级方法是更换主板。一个配有高速CFU和充足RAM的新主板可以大幅度提高系统性能。对初级用户来说,这是较困难的,但对于那些喜欢摆弄机器的计算机爱好者来说(或者在一个熟悉计算机的朋友的帮助下),这个过程不是特别困难。 Different upgrade methods can improve the PC performance to varying degrees, but for those older PCs, the best way to upgrade is to replace the motherboard. A new motherboard with high-speed CFU and plenty of RAM can dramatically improve system performance. This is more difficult for beginners, but not particularly hard for computer enthusiasts who love to mess around with the machine (or with the help of a computer-savvy friend).
