But so far, from 6 to 8GB is not much payback. We do this at the office but this is for those that run Virtual Box and the extra RAM is used there. Otherwise not much payback. At least it's cheap today.
How to find out? Ask the seller or maker. If they do not answer a pre-sales question you should not buy from them.
I'm looking at buying a new laptop. I'd really prefer one that has at least 6gb RAM but from what I've seen it's pretty easy to upgrade the RAM. My question is, are all computers expandable to 8gb or just some of them? I don't think all of them are expandable but my problem is I'm finding a lot of computers at places like Best Buy that don't state specifically whether they're expandable or not. Anyone have any suggestions as to how I can find out if they are?
