Just my estimation, who knows later AMD increase the price like what Nvidia did on their Pascal cards haha

Alright, you haven't tested Vulkan based Dota 2 right?

Can you please test it? It reduces CPU overhead so your CPU usage is likely will be lowered.

If you aren't using Z170 mobo then no need to go for anything beyond 2133MHz because it will be downgraded to 2133MHz by the mobo due to chipset limitation.

Same goes to OC, if no intend to OC then no point getting anything higher than the base clock.

Any monitor can be used for gaming, if you are tech savvy and emphasize on the specs of the monitor, like low response time, high refresh rate then you gonna prepare a lot of money for it.

IPS monitor with high refresh rate (144Hz and above) can only be found on gaming grade monitor like Acer Predator XB271HU which costs RM 3199 now.

Is the GTX960 your preference or you already own it? It is quite confusing that you put a hardware in "Games & software that use frequently"

After you installed the Vulkan based Dota 2 from Steam, you need to enable it in vconsole, have you done that?

If you want to upgrade to GTX950, only get those priced below RM 700, those > RM 700 is not worth.

"Gaming" is just a gimmick, all GTX950 is made for gaming.

5k build is a bit too much TBH for non-OC setup, I upgraded to 32GB for ultimate multitasking and rendering, the monitor choice is optional, I have chosen a QHD monitor since you got a lot of budget left, the extra amount of pixel can be used for more multitasking spaces (more contents can be shown).

No choice then, your CPU will bottleneck the GPU during heavy teamfight, getting a GTX750Ti will improve the graphics quality that you can run but not guaranteed will stay at 60 FPS all the time due to CPU issue.

No need, try hunting for 2nd gen or 3rd gen i3 in Garage Sales which is using same mobo socket (LGA1155).

Not all software use GPU as hardware accelerator, most of them are CPU dependent.

3D rendering software uses GPU technology (CUDA, OpenCL etc.) to calculate vectors/matrices/floating point etc.

If budget allows, you can invest in a more powerful GPU.

It depends on the price, if the price of 2nd gen i4 that you found is too close to 3rd gen then I suggest you to take 3rd gen instead.

Then you can go for it, i3 2100 should be good enough for Dota 2

Upgrade mobo and RAM? It is on a very aged platform (socket LGA775), you need to hunt for used items in Garage Sales if you want to change them.

If you are thinking to upgrade to latest platform (Skylake etc) then nope, you cannot do that, they aren't compatible, you need to change the processor too if you want to upgrade them to latest platform.

Both of them come with 2 RAM slots only, go for MSI B150M Pro-DH instead.

M.2 is an interface (connector), if you don't have any M.2 SSD then you won't benefit from it.

The SSD you bought is using SATA interface FYI.

Perhaps you need to elaborate more on your requirements (gaming resolution, OC/non-OC etc.), 6 - 8k is a very large budget.

Are you planning to get the rig within this week or can wait for few more weeks? If can wait then you might be interested in the upcoming GTX1070/AMD Polaris GPU, GTX1080 is too expensive to build at the moment.

The GTX1070 is under pre-order now, will be released in mid or end of June, price might change when release date draws near.
