I was planning to buy new PC soon and there are some things I'm curious about and I couldn't find proper answer on the net. I would be grateful if someone could provide meaningful answers or at least link to some resources which might explain the stuff to me.
- RAM speed - in description of Intel's Ivy bridge and Haswell CPUs it says that they support 1333 and 1600 Mhz RAMs. However, in all reviews of those CPUs I see tests done with 2133 RAMs. So do those CPUs support those faster RAMs? If yes - is there any performance increase between 1600 and 2133 in case of those CPUs?
- Power consumption and PSUs - hypothetical situation. We have a PC and we have 2 PSUs with different strength. Each of those PSUs is powerful enough for the PC. We run the PC with first PSU, then we run it with the second. Will actual power usage of the PC (at the plug) be different in both cases, and if yes - by how much (in % of difference in PSU's power)? What I'm getting to: will getting stronger PSU result in higher power usage of the build, even if the extra power is not needed?
- Assuming I will try to overclock CPU (planning to get i5 4670K) can anyone tell me how stable PC will be? I know it depends on how much I overclock, so let's assume it would really be minimal. I remember that years ago when I tried to overclock CPU, even only a bit, it made my PC crash every now and then.
- If I have built-in GPU in my CPU (is it even listed in GPUs section of hardware manager?), and a standard GPU - is there a way to make one app run with the CPU's GPU, and another with standard GPU, at the same time? I assume that using software rendering will not make use of CPU's GPU?
