Since no heavy workload, get a non-overclockable build to save cost.

Skylake system freezing bug has been fixed by Intel and manufacturers are pushing out the patch via BIOS update so no need worry about it.

Continue with Haswell or Skylake?

That's third party cooler issue, get those with Skylake certified then no more worries.

6.5k is a large budget and you didn't give more information on what build you are looking for, especially monitor/peripherals requirements, so I will just focus on CPU and GPU more.

Intel Core i7 6700 - RM 1384
Gigabyte H170-HD3 - RM 488
Corsair 8GB DDR4 2133MHz Value RAM - RM 200
Zotac GTX980Ti 6GB GDDR5 AMP - RM 2899
Kingston HyperX Fury 120GB SSD - RM 229
WD Blue 1TB HDD - RM 215
Seasonic M12II EVO 620W - RM 409
Corsair Carbide Spec-01 - RM 240
Logitech MK200 Wired Combo - RM 65
Acer S230H FHD - RM 399

Total: RM 6528 (Techview price inclusive of GST)

GTX980Ti might be a little bit overkill for 1080p gaming but it will last you for quite a while before you need to upgrade again, if you want a better monitor/keyboard/mouse/case then you can downgrade it to either GTX970/GTX980/R9 390/R9 390X etc to cover up the cost.

this one ?

That's why I don't recommend Malaysian to use PCPartPicker, the price is in USD and you cannot direct convert to RM due to different price (import duty/tax/GST etc.) and some items aren't available in local market here.

I added the market price to the items listed for your convenience.

G100 is not included yet.
If you downgrade to i5 non-K build then yes, can fit a GTX980Ti.

Bro, didn't terence_nwb suggested a few builds already?

This is one of them.

Old price though.

Are you gonna be overclocking, though?
