With 8k budget, you can go for overclockable rig, either Z97 or X99.
Intel Core i7 5820K - RM 1499
MSI X99S SLI PLUS - RM 974
Corsair 8GB DDR4 2133MHz Value RAM - RM 469
Liteon S900 256GB SSD - RM 429
Seasonic M12II EVO 620W - RM 379
Total: RM 3750 (Viewnet price inclusive of GST)
Zotac GTX980Ti 6GB GDDR5 AMP! - RM 2849 (To be released soon)
As for cooler, you can choose air or water cooler, cheap air cooler like CM Hyper 212X is quite reliable or you can go for liquid cooler such as CM Seidon/Nepton or even high end Corsair H100i/110.
As for case, you can pick your own favourite since you have budget to do it.
And last, the budget left after getting all the parts can be used to buy a monitor, it could be a cheap BenQ 24 inch which falls below RM 500 or high end Dell U2414H which costs nearly RM 1000.

Well, holy shit. Sadly I don't think I wanna go above 7k for multiple reasons.
What if I don't want to upgrade to overclockable rigs and still want to upgrade based on the first list you gave me? Preferably max 6k.
Terribly sorry for the troubles caused; I just wanna make certain of all the possible choices and consider them.
