Right now my system has 4GB of system RAM, which as far as I know is enough. However, the newest video card I purchased, the 6950, has 2GB of RAM. It seems odd that my video card alone has half the RAM that my motherboard does. Should I be using more system RAM? My primary uses for my desktop are gaming, Excel, Access, Netbeans... I do want to get into video sound editing soon too.

What OS are you using? Because if you use a 32 bit OS, 4GB is all you can use anyway.

I have 12 GBs of RAM and sometimes wish I had more. I use it for music composition though, with instrument libraries that can take up several hundred GB of HD space.

For editing or composition, I'm not sure you can have too much as they will typically use whatever you have. For something like a 64bit gaming system, I'd read somewhere that the 'sweet spot' for RAM was 6GB and that going to 8GB didn't really buy you enough to make it worth the money. That's what I ended up buying for mine and haven't seen a time where I've needed more... but then I haven't explicited monitored for that, either. I'll have to experiment some today.

FWIW, I have 2GB of video RAM as well, but 2x1 in SLI.

Here's the Tom's Hardware article I had read about 6GB of RAM. Also this about measuring usage and the fact that Windows 7 will attempt to keep your RAM fully utilized.

I'm using Win7 64-bit. Thinking I'll order another 2GB of RAM based off that article.

Just wanted to chime in that about 6 years late, I realized I could easily access the RAM chips in my old 2008-era HP PC (still "gloriously" Vista 64-bit), so I upgraded it from 4GB to 8GB (four 2-GB Crucial brand chips, about $140 total).

This turned Shadows of Mordor from unplayable, freezing slide show to shockingly smooth and playable. Also greatly reduced, sometimes eliminated constant hard drive thrashing. And I've been digging up games I gave up on due to poor frame rates and finding them a complete revelation now.

So my guess is 8GB RAM is a good minimum today, and a lot of folks insisting they need gaming PCs or $300 video cards might want to first try to upgrade their RAM first (if they were as low as mine anyway).  icon_smile

8GB will be fine for the foreseeable future.

However, I see 12-16 being the norm by the end of the console generation.

This is because, with the way PC games currently use the video memory on the GPU cards, it literally has to duplicate all that same texture and graphical data onto the system memory. And with graphics cards of 3-6GB becoming the norm, the duplicated data will take up the system memory.

That depends on game though, and future tech could allow better use of system or graphic card memory.

I use 16GB of RAM, mainly because I got tired of my 3D programs crashing due to out of memory errors, but I was surprised to see the latest crop of games start making use of some of that extra memory.

For some reason, Google is resisting me, but I'm pretty sure, based on my memory, and based on eyeballing Marvel Heroes using process explorer while it was active, that gpu texture data, etc, is no longer duplicated in system memory. It did used to be the case, but I remember reading that one of the recent... I'm thinking dx11 or 12, dropped that... Marvel  is definitely not replicating the data... it's using several hundred megs on the card, and only 25 megs of 'system gpu memory'.

I do still recommend 8GB as a new 'minimum' for machines...

Let's face it... memory is relatively cheap these days... and if your machine has to hit the paging file or whatever they're calling it these days, it's gonna chug. Mind you it will chug less if that pagefile is on an ssd.

When your web browser alone can hit over a gig of memory in use, it's much better to have too much, rather than too little.

For the record, I've not had to use any sort of swap in years (ever since moving to 8GB on my machines)... and I don't miss it at all.

I have 16 GB on my main laptop running Win7 64 bit which just so happens to double up as my gaming  laptop. I have to run Geographic Information Software on it to support one of my tech writing gigs. GIS software is noted for being a RAM pig and I've never seen more than 12 GB of resources consumed on it. I'm thinking you'd be good to go for a while with 8 GB.

... and she says it`s not the size of the buffer, but how you use it.

Hey, she loves me so she has to, right?
