MSI GT70 - which ones are required drivers and apps? Which ones are optional?

I have MSI GT70 0ND but I suppose lots of things will overlap with other GT70 even GT60 owners (Windows 8 x64). So which onces are needed and what are they? I will post some that I know, then ask you about the rest:

DRIVERS

Realtek HD Audio - is this the orange sound icon for additional effects? If Yes, then I will use it

Intel(R) Chipset - main driver, download

Intel N2230 Bluetooth 4.0 - is this the bluetooth driver?

Realtek Card Reader - is this for adding memory cards in the slot, thus the driver for it?

NVIDIA Geforce GT670M/670MX/675M Graphic Card - best is from Nvidia site, latest

(Beta) NVIDIA Geforce/Quadro Graphic Card - this is for some other video cards, I dont need that right?

Intel HD Graphics Family_Intel Ivy Bridge - now what is this? Does any1 know, so that I decide if I will use it?

Synaptics Touchpad - that's my touchpad

Intel N2230 Wireless LAN
Qualcomm WLAN Killer N1202+ Bluetooth - Is this like the above case with video graphics, just need to choose 1 of them for Bigfoot killer, or both? Which one should I choose?

Intel Rapid Storage Technology - no idea what this is for and if I need to install it... so what is it?

Intel Management Engine - what is this?

Camera - it's clear duh

Intel USB 3.0 driver - for my USB 3.0 ports?

Radio Switch - what is this?

Intel RAID - and this? do I need it? I don't do enhancenements with software.. so


UTILITY

Cyberlink PowerDVD 10 Blu-ray patch - so I need this to play BluRay?

SCM
SCM (Only for Windows 8 upgraded from Windows 7.) - I know this is screen contrl manager but do I really need it? Can't I do - disable.enable wifi, bluetooth etc from Win8 without it? I think I won't use it

NVidia VGA OC - this I would need only if I am to overclock my videocard, right? (which I won't do). So is my 675MX using the 4GB since total memory when you see specs shows 1664MB and I think it is dedicated?

Keyboard LED Manager - that's for the lights of the keyboard, ofc I would use that

THX AP
THX EQ - I see it is for the sound but is it something needed, what does it do?

If you could answer about those so that I know which ones I will exclude, would be great

 

No driver is "optional" in my book. The associated software/utility sometimes is, but you need a device driver for any device to communicate with the rest of the system.

- Yes, the Realtek audio driver gives you the orange speaker icon/Realtek audio utility.
- Your Bluetooth and WiFi driver may come bundled or separate. You'll need to sort it, although it appears you found a download for the deuce.
- Right, that's the driver for the card reader slot. Without a device driver, the system won't recognize any SD media.
- If you have a GeForce card, then no, you don't need that. It's a BETA driver for NVidia Quadro cards.
- This is the driver for the Intel graphics. The CPU has an integrated GPU. It's a good idea to keep that current.
- That looks like the aforementioned bundle for your NIC + Bluetooth. Since it has both drivers (Bluetooth and WiFi), use that over the standalone Bluetooth driver.
- This is for hibernation. It will require a partition on the hard drive equal to the amount of system memory. If you use it, keep the driver current.
- Intel ME is a sub-OS thing. Keep it current. Here's a detailed description of it.
- Yes, for your USB 3.0 ports.
- RAID in this case is for either striping or mirroring data (RAID 0 or RAID 1, respectively). There are other RAIDS, but if you're not utilizing either, you don't need to worry about this one.

- Yes, you'll be needing that to play BluRay.
- Optional. If you won't use it, put it on the wayside.
- Yes it's for OC'ing. Not sure what you mean by the second question though.
- It's more of an enhancement suite but not entirely necessary. It will give you additional control over audio effects.

I hope I covered most of it, at least!

 

Here raise up the same question too.... what is it exactly???

 

WiFi toggle.
