as above, the LGA1156 platform is no more dead than 1366. if anything, 1156 will last longer. (i really don't know where these rumours keep coming from, but they are being spread by people without a lot of knowledge in these things)
as above, the i5 is actually a superior gaming processor, the 920 being better at encoding tasks and such. the gtx460 is also the superior GPU, so this is a no brainer.
