Okay, second time making my reply as I accidentally clicked previous page on my mouse. This one might not be as in-depth so sorry about that. What I basically said was that a bottleneck means that one PC component does not compare to another component. So basically if you have a very bad CPU (processor) and an extremely fast GPU (video card), the CPU will hold the GPU back, power-wise. I quote here, a good example of a bottleneck: ''say you have a rubbish CPU, it can send 50 bits of data to the graphics (video) card per second, but the graphics card is able to process 100 bits of data per second. So basically, the CPU is holding the GPU back because it is not sending enough info to the GPU to keep up.'' Like TONSCHUH said, this was probably the case with the rig you posted earlier. Now for the new rig you posted. That's miles better than the previous one. The FX-4100 is a very decent quad core CPU, which definitely lives up to (or above) it's price tag. I think it's also safe to say that the GT 640 is a very good mid-range graphics card capable of playing pretty high end games. I've seen it play Crysis 3 on extreme settings running on average at 30 frames per second (which is very reasonable), sometimes dropping to 20. The FX-4100 should definitely not bottleneck the GT 640 as one of my friends is running that CPU perfectly with no problems together with a GTX 660. Your new rig (or soon to become new rig) is definitely a good one, and I would estimate it to run Arma 3 at around mid to high range (most likely high) settings depending on your resolution and fps you want to play at, if 30 FPS and a 720p resolution (console level) is fine for you, you could probably ramp the settings up very high, if you want to play at 60 FPS, perhaps with a higher resolution (if your monitor supports it), you'll still be able to play at quite a high setting. Add CPU and GPU together with the 8 GB of GDDR5 RAM and not to forget Windows 7 (not that horrible OS that is Windows 8) and you've got yourself a fine machine (PSU, Motherboard etc.. are not very important in this case as it is a pre-built machine). One last thing though, have you thought about building the PC yourself? Really saves money and is also pretty fun. My first time building a rig was fun anyway and it all went smoothly, I recommend watching Newegg's PC building tutorial. It's great and will help out a lot, ( link for part 1). If it seems like too much of a hassle, go for the LanWarrior rig you posted.Now this has still gotten pretty long so I think I'll stop here. I hope you found this useful. ~Peace
