I would personally not get a blu-ray drive unless you plan on watching movies at your computer. I use my ps3 as a BD and I would much rather watch a movie on my 52" rather than my 22" monitor. The monitors are completely up to date with it, and graphic cards are well past BluRay quality graphics. However, you do have to get a fairly high-end card... although nothing over 150 bucks. Whether or not you get a BD is up to you, but looking at your sig you should be able to play blurays without a problem at all.
