How so?
Last I checked, a pair of old RCA cables can move two analog channels of audio. HDMI will carry up to 8 channels of up to 192kHz/24-bit audio.
Though it's rather a niche segment, many people watch a sporting event and tune into the radio broadcast coverage of the game to listen to the radio announcers. The team's own radio announcers are oftentimes much better at knowing what the hell's going on than the ones on TV.
Core i7 940 -> $564.99 + about $250 for mobo = $800+
Phenom II 940 -> $224 + about $150 for mobo = about $375
Core i7 needs DDR3, Phenom II 940 runs DD2 (note that the 940 is an AM2+ part, not AM3 so it doesn't support DDR3). DDR3 is somewhere around 50% more expensive than DDR2 (though falling).
For me, the fact that the i7 is only about 10-20% faster than the Phenom for more than twice the cost, it's simply not worth considering for me. Then again, I do most of my gaming on consoles.
