Best Chip to get?

[Pyrokar]

hi,

i have a question regarding x2 lite & pro.

The newbie guide says, that x2 pro is the most recommend chip to purchaise. Now i want to know what advantages you have by installing your own Bios (x2 pro) rather to use a preinstalled one(x2 Lite). Can i update my bios with x2 lite the same way i could with x2 pro?

please don't judge me for my question, i know i am a noob, but it would be very fine if you could help me.
