It does start to show where i7 starts to have an advantage...specifically in CPU-intensive games with no less than a pair of GTX-260 or 4870 videocards in SLI/X-fire, and even then sometimes only when driving low resolutions noone would run such a graphics combination on. Yeah, I thought that part of the test was a little weird...but it does show that as time goes on i7 WILL distance itself from both Phenom II and Core2Quad, and that is an important point.
However, while i7 prices have steadily become more reasonable, what still deserves note is that an AM2+ system based around a 940BE and DDR2 RAM still comes in ~$150 below that of i7. You just have to ditch DDR3 which doesn't help Phenom II anyway (for that matter it often doesn't help i7 either). And as ironic as this may sound, there's a very real possibility that socket 1366 will end up having LESS of an upgrade path than AM2+/AM3.
Consider: It's already official that the current i7s on LGA-1366 are going to be gradually phased-out, and it's increasingly looking like the socket will be reoriented toward server applications. As far as I've seen there's no guarantee LGA-1366 will see ever 32nm chips in anything other than server chips, and Intel's first 32nm chips are going to be dual-cores (i3?) for LGA-1156. In the meantime processors that were initially used to represent the performance of i5 are now being called i7 for LGA-1156. System builders thinking their new LGA-1366 board is gonna last through 5-years worth of processor upgrades may have another thing coming. In the meantime AMD oddly enough has announced that they're releasing 32nm chips in 2010, even though Bulldozer isn't supposed to arrive till 2011. Will AM2+/AM3 actually see 32nm domestic chips? Who knows really with that one.
Now I could be overthinking with the LGA-1366 deal, but it's not stopping me from holding off on i7 for the next little while. Fortunately with the graphics setups and resolutions I happen to be running (both a Phenom II and a Core2 setup) i7 isn't presenting any advantage yet anyway. But this multiple socket deal has seemed funny to me for some time now, and every new article I see on the matter seems to reinforce my suspicions.
And it's not like it hasn't happened before, either...AMD pulled similar antics with sockets 754/939/940/AM2.
