I disagree. Sometimes I can afford the best CPU, but it's twice as much as a CPU that's 90% as powerful. It doesn't make sense to buy it, even if I can afford

I disagree. Sometimes I can afford the best CPU, but it's twice as much as a CPU that's 90% as powerful. It doesn't make sense to buy it, even if I can afford it. I can wait a year or 2 and upgrade and still save money over buying the best. The same goes for memory, hard drive, and other parts of the computer.
