Do I really need more than 6GB of RAM?

Intel's DX58SO only has 3 triple channel RAM slots (and a useless single channel slot).

I plan to put 6GB of DDR3 RAM in there...will I ever need more, or would 6GB be good enough for
say 4 years?

Otherwise I might just get a Asus P6T and get 6GB now with the possibility of 12GB in the future.

Well, honestly, it's hard to say how much RAM will be the norm in 4 years. Chances are the computer is gonna seem "slow" by then anyway. But i'd still go the ASUS board anyway, better quality.

You won't need 12 Gb in future .Your computer will be outdated by that time.
6 gb is more than enough.

But don't buy that intel board cuz they are Poor quality and they don't overclock.

If you are gaming, or primarily using just one program at a time, then 6gb is plenty. There are very few applications written to take advantage of more than 2/3gb of ram. Photoshop CS4 is one, I think. Even if you are doing a modest level of multitasking, then 6gb seems to be enough.

You could get a 8gb kit for the intel if you wanted, and run in dual channel mode. Performance would not suffer.

I see. Thanks, I'll go with 6GB then

When there are 4GB sticks of RAM you'll be able to use 12GB anyway. Sure it's not the 24GB that some people will be using but I doubt you'll be using an i7 system by the time you need 24GB
