2all you player/RAM hater out there /* jk */
You wouldn`t need more than 4GB?
My win7 x64 grabs 2GB just to be alive and I even disabled all this crappy aero-stuff!
Ok, that would be about 2GB for the game, which i think isn`t that much.
I`m RAM addicted, don`t listen to me, but going for 6GB is enough to be on the safe side, wouldn`t it be terrible to have 100% of your RAM beeing used while gaming?
The other thing I have to say: Which game really needs a six-core CPU?
I think none, but you buy a better CPU than you need, so why not buy a bit more RAM? I have said, that i`m RAM addicted... <3
If you had 2GB of RAM, 7 would use ~750MB of it.
And when an application needs the RAM, 7 will give up it's resources for said application. So have fun wasting your money on more RAM when it's completely not needed.
