Drop the Z170 mobo and high performance RAM, use the extra money to get i7 6700 instead, some games are very CPU demanding and the i5 will somehow "bottleneck" the GTX1080 when it can't cope with the heavy CPU workload/demand, this is often seen in open world title and heavy multiplayer based title. Fast RAM does benefit Skylake CPU but you need a strong CPU foundation first before spending so much in a Z170 and high speed RAM, it is just a waste when your CPU doesn't even have the chance to fully utilize them due to "bottleneck".

Intel Core i7 6700 - RM 1300
Gigabyte H170-HD3 (D4) - RM 446
Corsair 16GB (8GB x 2) DDR4 2133MHz Value RAM - RM 322
MSI GTX1080 8GB GDDR5 Armor - RM 2852
Seagate Barracuda 3TB HDD - RM 409
Superflower Leadex Gold 550W - RM 409
Corsair Carbide 400C - RM 485

Total: RM 6223 (ETech price inclusive of GST)

Is 3TB HDD really necessary for now? If yes then you need to downgrade other parts, like mobo/case to keep below 6k, otherwise you can just get a 1TB HDD (costs around RM 220) for the time being for storage.
