Dual Channel Vs triple channel

[Riccardo_80]

Hello!

I need to change my pc, i have seen different configurations at different prices, and one point in particular it's not clear for me: triple channel ram is real better than a dual channel? I use Photoshop, flash, premiere and after effect. And on new pc i will install windows7 64bit.

thank for your help

RAM performance is not really an issue, it won't drastically change overall performance levels for all but synthetic workloads.

Take a look at some benches:

Focus your energy somewhere else; memory is not key to performance as its no real bottleneck.

thank you very much, i'm looking the benches ,
but if the ram is not the only problem, is it better an i7 870 than i7 920( is it better to choose a dual channell processor faster than a triple channel lower), and the motherboard from dell are good? ( i've seen some pc from dell site with a good price), and for my software is the video card important?
I'm sorry if i'm not very clear but my english is terrible

Get the i7 920 because it can be overclocked to very high speeds. In the future your graphics card might be important for adobe photoshop etc., but right now it is not important. You might want to buy an Nvidia card because adobe products might use CUDA in the future.
