fast memory vs latency is there much a difference either way? i know theres an article somewheres but googled it and couldnt find what i was looking for

Speed and latency is the main factor to determine how fast is your memory.

For example:
DDR3 1600 CL 6 vs DDR3 2000 CL 9.

To put it on simple maths:

The frequency is expressed in Hertz, which means "cycles per second". So, the DDR3 2000 will perform 2000 cycles a second while the DDR3 1600 will do, well, 1600.

The CAS latency is given in cycles. So, a CAS9 RAM will take 9 cycles to respond and the CAS6, 6 cycles.

Now putting it together: the DDR3 2000 CAS9 will take 9/2000 seconds, which is equal to 0,0045 seconds, to respond while the DDR3 1600 CAS 6 will take 6/1600, which is equal to 0,0038 seconds, to respond. Thus, the 1600 one is faster.

There is no practical difference. You might get up to a 2% performance boost in games. The only time it makes a difference is when you use very specific applications. The kind of stuff the normal every day user doesn't even know about. Don't worry about timings. Just get reliable RAM.
