I agree; 4 GB of RAM is more than enough to perform day-to-day tasks involving social media including YouTube, Facebook, Twitter, etc. You should be able to do some light gaming on a computer with 4 gigs, too - although gaming relies more on your graphics card than the RAM installed on your system.
My current computer only has 1 GB of RAM that's physically installed, with 1.5 GB of swap space. I'm able to surf the web and watch YouTube videos at 480p just fine. I
am able to play some movies at 720p too, if I resize the VLC window properly. Playing video games and YouTube videos relies more on your graphics card though as I said.
I'm going to build my own PC very soon (tomorrow, Thursday or Friday but no later than that as I already have most of the parts I need, just waiting on the PSU to arrive). It will have 8 GB of RAM but that's primarily because I plan on gaming with it.
My new computer will have the following hardware specifications
- Intel i5 4690K
- MSI Z97S motherboard
- MSI R9 270x
I'm going to use the 1 TB HDD and the 8 GB of RAM stick that I have in my old computer (not really old, but the CPU socket on the motherboard is fucked) in order to save money. The power supply is 700 watts, not a fancy efficiency.
So yeah
