I have a Dell XPS 8700 i7 4770 win 8.1 64bit 460w ps.I have a spare slot and was thinking of adding a blu-ray combo drive read&write capable.But after reading comments in Both amazon&Newegg I'm really confused,they talk about bare bones &firmware and no software.Some come with cable and a cd (I'll have to check in YouTube to figure how to install w/cables(where to plug them in))Bottom line is I'm really confused plus I don't want to spend alot($60-$90?)I need HELP and suggestions and guidance PLEASE....Thanks
