I have a four-core 955 Black edition thingey. <br>
It was originally running on 4GB but I doubled it to 8 GB.<br>
The result was astounding because I could now run <br>
multiple applications with little or no degradation.<br>
<br>
But there is no point in upping the RAM speed if it outpaces the
CPU. <br>
I always go by the manufacturers recommendation. This usually<br>
comes in the motherboard's user manual. Hence a preference for<br>
home builds. The build takes about an hour. It's the O/S install <br>
and configuration that takes most time.<br>

Looking at AMD buldozers:
<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Bulldozer_%28processor%29#Processors">http://en.wikipedia.org/wiki/Bulldozer_%28processor%29#Processors</a>
something like a FX-8100 or FX-8140
Questions:
1) For the sake of a few extra pounds is it worth going for more GHz - I suspect not
when getting to the high end - you just pay too much for the top of the line.
2) I suspect that speed to memory is very important - more important than raw
CPU speed - else the CPU just spends time waiting for data.
So high memory frequency seems 'a good thing'.
A DDR3 speed of 1333MHz seems to be the highest speed of the sensibly priced CPUS,
some Intel ones go to 1600MHz - but the CPU RRP is $,1000+ -- out of my budget.
But I seem RAM as quoted to go to 2133MHz ... does anything (sensible) go
that fast ?
A large cache will help - the AMD CPUs above have 16MiB cache (8 + 8 of L2 + L3).
I don't know if you can add the L2 & L3 like that;
It is hard to find the data rates to L2 & L3 - also to main memory (frequency
isn't everything)
Anyone any pointers ?
Just look at the huge number of processor code names that Intel has, confusing
or what ?
