I needed to change, because of my previous groupset were broken. The bb were crushed into pieces. I think that's from my last cycling at the Elmina offroad. So, a broken BB justifies myself for a new XT groupset.
It took some time for me to choose, whether to get the XT, or the SRAM X9. There's slight difference in price, but not much on the weight. To my observation, it seems that the X9 is much more sturdy than the XT. The X9 red version looks tempting too.
However, to my final decision, i go with XT, as i think Shimano is more commonly used between my friends, and i think XT groupset is better suited for my kind of cycling level. (eg. not a pro.. yet!). I took the groupset without the brakeset. I don't need a new brake for now.
There's a lot of significance difference between those two (XT and X9), however, i'm not going to explain them here. Those info are widely available, use Google!
