How much ram should I buy?

I have 2 x 4gb sticks of Gskill sniper 1600mhz ram currently installed in a gigabyte z77 udh

I want to get a bit more memory and was wondering the best way to go about it while keeping the benefits of dual channel or any other optimization ability.

Should I just buy any stick of 2/4gb of ram and plop it in? or will that mess with timings and such? or should i put 2 sticks of 2gb in? Would that allow quad channel?

I ask because I seem to be using up all 8gb of my ram rather easily ever since I enabled the Rapid Mode on my Samsung Evo which uses up to 1gb of ram for caching. Windows after a clean boot uses 2.5gb ram. With some chrome tabs open and cod ghosts running im easily at 7gb+ram usage.

First of all 8GB is good enough for your requirements. If you still want to increase the capacity of RAM, your best option is add 2x4gb sticks of G.Skill sniper 1600 mhz with same timings and serial number.

This will not be a quad channel but two double channels. Not all mobos support quad channel and not all RAMs are quad/dual channel enabled.

The 2x4gb sniper kit is $100 which is pretty expensive for me right now.
I likely only need maybe 2-4gb~ more
What are some other options I have available to me that cost less but still maximize memory bandwidth?
Or maybe its time to buy a new kit altogether? a fast 16gb kit 1866 perhaps?

8gb WAS enough for my needs for the longest time but Rapid mode seems to cache excessively which drives ram usage through the roof it seems at least in my case. But in returns it gives me 1200mb/s read and write speeds which is mind blowing.

If you have budget then go for 2x8GB kit. 1866MHz is good enough. Make sure the CAS Latency is 9 with this speed. It will give you good overall performance.

ideally I would like to just add another 4gb stick to my system or even 2 x2gb since that would be be cheap and suffice for my needs but I am wondering what would the effect be on my system if for example I installed this kit? would it work in quad channel mode? would the cas be messed?

It all depends, if rams are compatible then it will work. No, quad channel will be formed only when mobo supports quad channel and ram supports quad/dual channel. In this case you would have say 2 dual channels
