12GB Triple Channel. I upgraded from 6GB TC and didn´t notice any change at all, only in my credit card bill.

i went from 4 to 8 and did notice some differences in smoothness

Lots of people have 6 GB in triple channel now. How did you leave that one out. :)

I figured 8 gig would be more than enough for a few years...at least from a gaming point of view.

8Gb here.

ive got 3 gig ! let me vote !

12 Gb, like it says in my sig. To be honest, I'm not sure I've ever had it all in use at once! Pootling around solo in CloD, the CPU rarely seems to be going over about 60% usage per core (and doesn't use hyperthreading at all, as far as I can see). Sadly, the GPU hits 99% usage, and runs at about 80 °C - I'm not going to need to use the central heating in winter. :grin:

12 gigs, but that's for video editing in Adobe Production Premiere Suite CS5.5 - a 64-bit program that can use it.

..8 if my memory serves me right..:confused:

6 gig
