<p>How much would bus speed be factor in the overall decision? Unless that is, you buy fast components and expect bus speed to catch up?</p>

Trying to get my head around the soup of different names.<br>
<br>
Looking at AMD buldozers:<br>

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