I'm now struggling whether i should buy i7 or i5, as Microsoft announced that I9 will be available in the LGA-1366 platform, which maybe a very good upgrades against any I7 current processor. Somemore the Triple Channel RAM is kinda attracting.

Thanks for all your suggestion, I really appreciate it. By the way, it really makes me rethink the question : "Why should i need to have so many thread?". Well probably that is the most critical question to be asked.

I think I would get i5 core then, or high level of i5 ( which is i7 on LGA-1166). And I can put the rest budget on my new ATI Radeon 5870 graphic card as the benchmark is awesome.

But since now there aren't many LGA-1166 motherboard in the market currently. Most probably I would purchase my CPU by December. So hope that my estimate RM5k can drop till RM4.5k by December and there will be more nice high end motherboard for LGA-1166.
