Hello! This is my first post and I have a question at the same time. I am a pro gamer. I want to make my home as home theater. So I am looking for a projector which will deliver best quality picture and at the same time it will provide best performance for gaming. It is really hard for me to choose right projector. Because I never own a projector. I have read so many article on it. I have found BenQ HT2150ST I think it will be right one for me. It is around $700. My budget is around 500-800$, Now I am really worried. Should i go for it or not? Another question is that should i buy another sound system for that or built-in speaker will work fine? Thanks in advance!
