The problem with the old computer is the hardware, and the chipset instruction sets available to the software to use, both applications and operating systems. The newer softwares access more updated chipset instructions for activities like security, and new instructions sets for power consumption and application computations for graphics and calculations.
Basic rule of thumb, is that computer hardware has a usable life span of a maximum of about 5 years. . . after that, its time to get a new one if you want to keep your computer as secure and interoperable with the interwebs as possible.
Likewise, if you upgrade to higher bandwidth of internet services offered by the cable companies, the computer must be able to handle that level of throughput speed in the networking components, which are now part of the mother board or the chipsets in the cpu and mother board. . . so if you buy faster internet speed but have a 5 plus year old computer, you are wasting your network spend as you can't use all that you purchased.
