Depends on what you do with your machine.

If lots of Windows applications open then, Yes.

Lots of video processing work or graphics intensive work then, Yes.

Lots of database work or programming work then, Yes.

If your graphics cards use memory for video buffer storage and take it out of the normal memory pool then, Yes (you seem to have four cards).

After posting my answer to the other similar question (had a browser tab open with the question), I saw the link to this question, so I'm posting here, too.

My opinion is that you can never have too much RAM. It is arguably the most important factor in performance. I believe in putting in the maximum amount of RAM that the machine will take. I just upgraded a quad-core Core i7 laptop from 8GB to 16GB and it made a big difference. I paid $142 for 16GB but would have been fine with paying $189. I think you'll view it as a worthwhile expenditure. Just one person's opinion, of course, but that's what you asked for...in the other question. :)  Regards, Joe

Thank you db.
Should i stop at 16GB or should i max out at 64GB?

My opinion — max it out!

If you've got the budget and the need then max out.

you can always open task manager, and check how much ram is used and free!
but in general - more ram helps best

Definitely. The most RAM, the better (if you can afford it).
If budget is a problem, simply decide when the price overcomes the advantages. For example, I have seen in some cases that after a certain limit (e.g. 32GB) doubling RAM means increasing your budget by four.
In this case you can also decide to invest in some other hardware: ssd drive pricing is becoming very popular these days, and you can add some performance points by placing here working and temporary files if you do - as it seems - video editing.
Always take into account task manager and performance monitor data while doing your everyday task, to make a complete choice.

I shall give an alternate view.

I have a ThinkPad with 8Gb of ram (with room for 16Gb). It is fast and smooth and can handle 2 or 3 simultaneous machines just fine (virtual machines) along with the normal work.

I have a Desktop that had 4Gb and I knew it could use more. So now it has 12Gb (added 8). It is no faster than the laptop.

8Gb is ample for most loads and 16Gb certainly will handle anything. Beyond 16Gb - I would not spend the money.

Thank you Lee i think your comment was the most useful i dont see why i would need to spend over 500 dollars in RAM to play games.

> i dont see why i would need to spend over 500 dollars in RAM to play games.

You never said anything in any of your posts about using your computer only to play games. I obviously made a bad assumption about the reasons for someone considering an upgrade from 8GB to 16GB of RAM. Btw, it seems to me that dbrunton's earlier post (http:#a39915427) said pretty much the same thing as Lee W's post, in a bit less colorful language. :)  I think it's deserving of at least an Assisted Solution.

that also tells you if it is needed or not
