Tenchusatsu,

By your logic, no one should be buying 1 GHz processors either. All you're doing is throwing away hundreds of dollars for an extra 50 or 66 MHz. You'll end up with less memory, slower graphics card, slower and smaller hard disk, etc. Essentially, having a 1 GHz processor in a computer cripples the performance.

There can in fact a case like that. Suppose you have $1300 budget, and you spend $1000 of it on a 1 GHz CPU, and all you can afford is a 810 motherboard with 32 MB of 66 MHz SDAM, slow hard disk. Of course it would be crazy to build a system like that. For that kind of money, you could build a balanced system with say 750 or 800 MHz CPU that would not be swapping to disk all the time, and it would in fact outperform the 1 GHz system in most of the benchmarks.

The point is to spend money where it buys you performance. As far as RDRAM, it buys so little if anything that it should be the last thing you should spend your money on. Only after you spent money on a 1 GHz CPU, and every other conceivable trick to improve performance.

The Dell Optiflex system is a good example of unbalanced system. For example, they have one (something called Optiplex GX200), a 600 MHz system with 64 MB of RDRAM. For the same money, you could have 666 or 733 system with 128 MB of SDRAM that would beat the first system in EVERY benchmark, real-world or synthetic.

How do you justify such a system?
