I do technical computing (embedded systems) and learn shit like CPU design, OS architecture and assembly stuff. LOL. I know what I'm talking about... Besides: benchmarks are fuck all when it comes to the overal complexity of modern OS design and there's a lot more to a responsive system and overal performance than just linear (albeit parallel) tasks.
And? I have a Bachelors and Masters in Electrical Engineering. I have taken and aced semiconductor physics. I have been building computers for 15 years and made it through the 10 megabyte is god 90's.
1. Why buy 16 GB now when you don't need it. RAM is easily extended LATER when, and if, you do need it. So, like I said, buying 16 GB is a waste.
2. Yes you did say spend more to make the CPU wait less.
while a shitload of fast, realy expensive RAM can beat a much faster CPU with less and slower RAM.
A shitload of excess RAM doesn't make your system any faster if its unused. Buying a CPU with the largest on-die cache (L1/L2) is the best approach since the CPU will try to prefetch as much from the RAM data as possible for it's operations. Spend your money there and on a good motherboard which will allow you to overclock cheaper 1600 MHz RAM to 2000 MHz. Which is exactly what I did and saved over $100 on RAM.
3. What you erroneously refer to the RAM speed in your diatribe is actually the Front Side Bus (FSB) speed of the MOTHERBOARD. This is the heart pulse of the computer and dictates how fast everything can communicate. You can easily overclock RAM to
MATCH the faster FSB of a good motherboard.
Here's a marketing hint for you, VINCENT!, when a company sells you ram that is marked 2000x Ultra Mega Gaming RAM, ZOMG!!!, they are just selling you the SAME EXACT RAM as the cheapest variant (1600 cool RAM) except they have run the ZOMG ram through more tests to guarantee consistent performance.
This is the same exact marketing that CPU manufacturers use. They sell the same exact die architecture for chips that range from $200 to $800. The only difference is the location on the silcon wafer that the chip was made, the more desirable the location the MORE PROBABLE the CPU will perform to its rated standard for the rated time period.
