GT660R. What to do right out of box?

If all goes well, will be purchasing this laptop this weekend. I have made my final decision on that.



What should i do straight out of the box to get this working 100%?

What bloatware should i take out, anything i have to uninstall, like drivers and reinstall?



What should i know.



Few questions after reading through some more threads:

What is BIOS?

What is RAID?



Appreciate it.
