I'm building my first pc (A budget gaming rig) for 600$ and i'm trying to choose ram. I think i need about 8gbs but i don't know what speed i need. Can somone help me out?

Not enough to make it matter. CPU and GPU will be what determines how your gaming rig will perform. Using say DDR3-2133 vs DDR3-1600 won't make more than a couple of FPS difference. Use whatever memory speed your motherboard and processor recommend unless your going to do any overclocking.

Even with overclocking, memory speed will not make that big of a deal. Without knowing any specifications on your proposed "budget" gaming build is, I can almost assure you that you won't have to worry much about overclocking. Like I said in the last reply, just use whatever memory your motherboard and processor are rated to run at, usually DDR3- 1600. If you want to play the overclocking game, get the memory with the fastest timings your motherboard supports. That will mean you should be able to technically overclock your system beyond it's rated specifications.

If you are only doing gaming at one time and only playing one game at one time, it won't really be a very noticeable difference. CPU and GPU make the differences in speed and graphics, as well as a good monitor.

Google It.
 


I already did. The performance difference from 1333mhz RAM to 2400mhz is usually 1-3 fps, even in Battlefield 4.

With ram there is obviously MHz and timings/ latency.
The easiest way I can explain it is MHz is like a highway, the more MHz the wider the highway and the more cars (processes) that can go on/take place. Most ALL of the time the higher the MHz, the slower the latency, such as say 2133mhz with 10-11 cas latency. Latency is how fast cars travel through the highway. The lower the MHz, generally the faster the cas latency, 1333 MHz ram with 7 cas latency is very common. This is why the 2133 MHz 11 cas latency ram performs almost the same as 1333 MHz ram at 7 cas latency. Sure 2133 MHz ram can have more cars pass at once, but they do so slower.

Yes, it does matter, especially if you are using a GPU in place of a dedicated graphics card.

Don't you mean APU?
There is a significant boost in fps when running an APU together with higher MHz Ram on games.
Ref. JayzTwoCent tested this on BF4(Check Youtube)
On a system with traditional CPU and separate GPU there is no advantage of higher MHz Ram.
