Anything less then a quad core your going backwards..it's like me saying my old Pentium 3 runs video great buy one of those haha..why even consider anything dual core when the quad core boxes and about the same price and you get more bang for your buck..think about the future not the 35$ price..the new mx3 boxes for 50$ are the best deals....There is a huge difference between dual and quad core video playback
