Yes. 8GB is fine for gaming, 16GB is top-notch and anything more overkill. Nope. Open your case and look for the thing where your power cable goes in (pull it out before opening the case) - that's the part commonly called PSU (Power Supply Unit), responsible for converting the 110/230V your wall outlet provides into whatever your computer wants. On top of that box should be a label, look for the paragraph starting with 'Output' and tell us what written there - or even better, post a picture.

Alot of these Survival/Life servers are awful - make sure it's not the server capping you.

What is your definition of running? Barely? 24fps? 40fps? ((Just forget 60+ outright, it's not gonna mix with the 'limited budget' part.)) Graphics intensive or not? What sort of budget are we looking at? 1000$? Below that? Above it? Also, since we're talking about a limited budget: Is overclocking and/or used components a option?

If you want that game to benefit from your new SSD's superior performance, it obviously needs to live on the SSD. Feel free to make multiple partitions on your SSD if that's the way how you organize things.

His proposed rig already contains a SSD, so I didn't mention it. That's pretty much conventional wisdom if you don't want / cannot afford a all-SSD setup. No reason to not use a piece of hardware you already have.

Obviously not the best rig possible, but decent for its price and powerful enough to yield a enjoyable performance. You might consider a i5-4470k and overclocking to get more fps/$ though. Do not replace for Arma 3, especially since your budget is quite small.

Intel is much more important for this game. If it's a R9 of some description, you'd need a high-end i7 to max it's capabilities anyways.

Mag Repack needs Moduload to work across save/reload.

Just put 'if (1) then' there the next time around - saves a couple of opcodes in a already CPU-heavy game.

Be aware that achieving a stable 60+, either requires a top-notch machine (CPU-wise), or quite low viewranges. This guy has serious airflow problems on three of his four cards. Quad SLI's generally aren't worth it on single socket systems.

It's running fine on the TP, without significant performance changes. ((Generally, unless the application in question is a driver, or really old, it's going to work.)) Notebook+Arma3 is not exactly what I'd recommend, but if 'notebook' is a must have for you, the Y70 is a top competitor and will run the game fine (just a lot worse than a similarily priced tower). 54Wh? That's like 20 minutes under load. Geesh, that shop deserves punishment. For gaming in general: yes. However, like in many other places, Arma is a exception here, the game will benefit from every last Hertz you pull out of your (Intel-) CPU.

Beyond nVidia exclusive features like Shadowplay, no.

That notebooks' cooling is way to weak to sustain a full turbo and load on the GPU. ((Seriously, though, if you really want Arma 3 on a notebook, go for one advertised as gaming notebook - virtually everything else (except some business devices with Quadro/FirePro chips) won't net you it's full potential for long.))

It's a notebook. There are ones with good cooling and ones who can't even keep the stock frequency (and anything in between).

Asuming the cooling concept is good enough.
