2x4gb or 1x8gb

[BBMadrides]

On a website one 1x8gb ram is worth $59 and a 2x4gb ram is worth around $70
which one?

1 stick is better because you have more slots to Upgrade in the future

Although 1x8GB provides less memory bandwidth, it's cheaper and takes up less slots. I'd also buy 1x8GB.

some people say 2x4gb is better because it has dual channel, does it really make a difference?

 

[George Phillips]

It will make some difference, but not much. I have run systems running with single memory/channel without feeling slow during day to day office/web browsing tasks. If you need to run memory access intensive applications, it's best to do dual or even quad channel memory whenever a motherboard can support either one.
