I need help choosing a receiver for my home theater system. I have looked around at many different review sites and none of it is helpful. I have just purchased Polk RTi12's, FXi5's, CSi5, and a PSW505. For my speaker wire I purchase Cobalt Cable. I was wanting a receiver that I could run my PS3, Xbox 360, Nintendo wii, and my PC through into my Samsung 1080p DLP. This is my first time purchasing equipment like this. Everything else before this was home theater in a box. I really need help with this and look forward to your opinions. I am trying not to spend anymore than $1500. Please Please help me!
