There is a new GTX1060 variant which spots a faster GDDR5 memory module (9 GT/s vs 8 GT/s), not sure if it has arrived in Malaysia or not yet, you may wait for it if you want. Another GPU choice is RX580 8GB, the performance of RX580 8GB and GTX1060 6GB is almost identical (some favor one another) so it depends on you which path to go, GTX1060 wins in power efficiency and cooling whereas RX580 wins in DX12/Vulkan titles and the extra 2GB memory. Same goes to CPU choice, AMD Ryzen build is also possible but if you are going to use the rig for gaming only then Intel is still more preferred.
Yea that's a nice combo, good IPS monitor from Dell, but bear in mind that some people might argue that the 6ms/8ms response time of that Dell monitor is not suitable for gaming, trust me, if you don't play any fast pace games or have a pair of "eagle" eyes then it is completely fine, I do use my U2417H (8ms) for gaming too and I don't find any problem with it, the super thin bezel of Dell UltraSharp monitor is just too nice
