I was considering getting a 2x4GB to start of, but as it turn outs, dual channel doesn't really matter: There's a benchmark @ gamer's nexus .net, at guides/1349-ram-how-dual-channel-works-vs-single-channel?showall=1 [I'll edit this in a few posts
]
I will buy a second identical ram in 6 months, and as the maximal capacity of the CPU/MOBO is 32Gig, I don't want to get stuck under it for no good reason. I'm
not sure I'll
ever have 32 GBs... well, that's not true: I'm
fairly sure I'll
never have 32 GBs of RAM, but still, why not keep that door open, if it costs nothing and I lose virtually nothing.
I'll give a thought to not having a HDD in the future, it does sound reasonable. Or having a HDD which I only power up if needed.
