I've been quite ... not to dampen the mood but I've waited the best part of a year for the 8 core processor - OK I'm willing to put up with the fact they turned off 2 of the cores but I can definitely wait a little longer for a Retail.
Not overkill! on RAM
I'm going for 8*8GB (2 x quad channel) only 1600 though - will be pulling one or two ram disks out of this
And with respect to a case, mine is being built in a P280(antec) water cooled + 2 * 79(50[or]70) - Will be creating a project log once I have most of the bits and pieces which should be end of next week (fingers crossed).
You have to set a limit somewhere! The money you save on the less important bits is the money you can spend on the actual tech.
EDIT:
Crazy price on 3930K at OCUK - wow bargain at 431.99 SO TEMPTED!
