Instead of buying a new PC for Blu-Ray playback I need to upgrade my Pentium D 2.8 processor (2 CPU's) and I've searched this forum/threads and I see the Q6600 mentioned and E6600. I don't game on it - just want CPU support for playback of HD movies on it (I already have the BD player, software, etc) and know I need to upgrade my video card. Given what I use it for (aside from surfing, Win 7, and Office programs) what is a good CPU without too much $$ since the Q6600 is @$300 and I could buy a new system for $100 more (though not w/that high of a processor but you get the idea).
