That monitor is by far the weakest component in your system. I'd say out of everything you'd get the largest benefit from upgrading to a larger, higher resolution monitor — an upgrade which would give you good reason to update to a newer graphics card. The GTX 1060 or RX 480 are fine to run 2560x1440 resolution monitors, which have about 2.84x as many pixels compared with your current monitor.
Regarding your RAM, you might be able to overclock what you've got, as your motherboard officially supports RAM OC up to 2200, but the RAM sticks you have might not overclock well as it appears to be budget RAM. Any low-latency kit at 1600 or above would perform well at any overclock. The main thing that would help going forward would be upgrading from 8GB to 16GB. I'd suggest just picking up a 16GB low latency kit like G.Skill ripjaws or something like that. When you're looking at the options at a certain frequency, just pick the kit that has the lowest CAS latency for that speed.
I'm really sorry for a very late reply
thank you for your advice, I honestly didn't really can OC as my cooler was only a simple fan. I always thought that OC need at least a better cooling system. CMIIW
The reason why I purchased that MB is because back then in 2012 I was told it was a decent option/ maybe the shopkeeper were succeed in fooling me into buying more expensive parts
because as u can see my psu 700w was too big for my settings,
since then I decided to learn more before I upgrade
btw,I looked at my ram case it was Corsair Vengeance 2x4gb
I don't know whether it was a budget part or not.
I think I'm still gonna stick to 8gb for at least 2 more years.
and I've purchased the new monitor LG LED 20” 20M38H-B FHD(1600x900@60Hz)
it's still a cheap one as I bought it only for USD$ 83
but still a lot better than the old one IMO
I decided not to buy a big monitor as I decided to save the money
to buy the USD$ 316 ZOTAC GTX 1060 AMP edition
It was really expensive in my country but as I was still bit lucky
because in other shops, people only got a normal edition of Zotac GTX 1060 for the same price
