Can i stream minecraft on twitch with 8gb?

Is 8gb ram enough to stream minecraft on twitch with obs? And are these specs good enough? I'm not looking for some crazy good gaming computer, I just want to play minecraft and I plan on streaming on twitch.tv so it just needs to be able to do that. Here are the specs:

First computer: Amd 6-core fx-6300 3.5 ghz unlocked processor, NVidia GeForce gt 640 gpu, 16gb ram.

Second computer: amd 8-core fx 8320 3.5 ghz, radeon hd 7850 gpu, 8gb ram.

I did some research and found that the 8-core and the radeon hd 7850 gpu is a little better, but I'm just worried about the 8gb of the second computer.

8GB is plenty aslong as you only have the recording and minecraft running.

Should be fine
