Thanks for all these great answers (except hclarkjr).I also know that they are not expensive,but let's not forget that they are not that cheap for everyone.They can get quite expensive (at least for me) if you are buying very high mhz ram
Only if you want to keep up with the Jones'. And people still play that game?man, i guess 4gb isn't the norm anymore. guess i need 32gb just so i can play farmville.
Not quite true. Windows gives a 32-bit program a 2 GiB memory address space. There is a "large address aware flag", that can force the Windows to give 3 or 4 GiB address space to a program, but not all programs are stable with that.
Programs that use pointer arithmetic based on assumptions of the greatest memory size returned to them can start referencing invalid or incorrect memory locations.the LAA flag was created out of FEAR that programs MIGHT become unstable if given that much ram (and I don't see how that could possibly be)...
Some 32 bit device drivers cant handle the extra memory and behave incorrectly, which is why Microsoft kept the artificial memory limitation on 32 bit Windows.but as far as I know that was unsubstantiated and there has never been a program which actually get a bug related to LAA being turned on.

Interesting. But they kept the limit for 64bit as well (at least, its on by default unless explicitly turned off by the program) and those had to be rewritten...Some 32 bit device drivers can’t handle the extra memory and behave incorrectly, which is why Microsoft kept the artificial memory limitation on 32 bit Windows.
64 bit drivers have to be rewritten anyway, and also won’t get WHQL if they don’t work properly with lots of RAM.
So what is difference in mhz?
Example: 8g (2x4) with 2600mhz vs 8g (2x4) with 1600mhz? Is it something i can see from my own eyes or only through benchmark programs? How big of an impact does have with 2600mhz over 1600mhz. The 1600mhz rams are usually cheaper.
The overall score, which is heavily based on the graphics tests, shows a mere ~1% change across the board. When you get to the graphics test, you can see that the faster memory makes absolutely no difference at all. It's not until we get to the physics test where we see some improvement from increasing the memory speed. We get performance boost of up to 11% when going from DDR3-133 to DDR3-2133. The combined test entails the rendering of a 3D scene with the GPU while performing physics tasks on the CPU. Here again, were see a very small 2% increase in performance from the slowest to the fastest.
