Storage and speed

What will you choose large size of RAM but slow speed or small size of RAM but fast speed

The chances of you noticing any real world differences would be incredibly slim.

Edit : To clarify I was refer to memory speed.

Personally, neither. But what's your usage?

[peterb]

RAM that is too slow will degrade performance, as will too little. So match RAM sped to the system bus clock, Athens install the minimum you need for the system to run your applications correctly. For most systems, 4GB of RAM is the minimum, some applications like video editing, may require much more.

It really depends on the application you're planning to run and the CPU/MB you're trying to match it with. Technically, some programs are better on utilizing the amount of memory over speed. Let us know what system is for and I am sure that some of these folks here will be more than happy to point you in the right direction.
