actually i would advise you to get the lowest end core i7 (core i7 920).
best bang for the buck.

motherboard:
there's still few hardware support for this new chipset, my suggestion is that you get the asus p6t deluxe.

memory:
buy good quality memory. my suggestion is kingston.
this chipset requires ddr3 memory and the board holds speeds up to 1600mhz.

graphics cards:
that really depends on how much you're willing to spend. my suggestion is the geforce 8800 gts, don't botter geting the 9800 gtx, the performance gain is not worth the price difference.

cooler:
if you're not into insane overclocking a good and easy to install cooler like the asus triton 81 should be enough.

monitor:
if you want to see hd, make sure you get a full hd 1080p monitor.

blu-ray drive:
avoid lg. yes they are cheap, but you will regret later.
