Here's more than you wanted to know...
If you want to buy the components today:
- the Asus mobo is good. There's always the Intel DG61AG
- As CES mentioned, there's little difference in idle power amongst the Intel CPUs. Also, load power is dependant on the load...not the TDP. So, an i3-2100 uses the same power when you watch a movie
as an i3-2100T. No reason to spend the extra $'s for the T designator.
- You don't say whether you do any ripping/encoding. If you don't, an i3-2100 is fine. If you do, then it's a matter of money vs time
for quad core vs. dual core.
- HD2000 vs HD3000. Doesn't matter if it's just DVR/TV/watching BD disc functionality. Might matter if you rip/encode.
- HQV scores
and the ~24Hz thing
. Pretty subjective and doesn't matter much if it's just time shifting TV. If you watch BD in film mode, then lack of true ~24Hz syncing might bug you. YMMV. If you are particular about this stuff, get an ATI HD6570 card.
If you want to but the components in the next couple of months, the Ivy Bridge CPUs will mostly all be out and the early motherboard firmware revisions will have settled down.
- I really like the new ASUS boards. Great fan control, you can easily underclock the CPU, etc.
- The iGP gets a bump in processing power and does a better job with HQV. ~24Hz is better but not perfect.
