i was thinking of going with the Intel D875PBZLK Motherboard ( link: http://www.pricegrabber.com/search_getprod.php/masterid=717830 ), but that was 2 or 3 months ago and i didnt know if there was anything better out now. also, i dont really PLAN on overclocking, because this is going to be a pretty quick system reguardless, but ive got 7 or 8 fans in this bitch so how fast, while still running stable, will the processor be able to overclock? 3.2 > 3.5? 3.6? what motherboard will i have to get to allow me to do this, but still have the featuers of the intel? ...and whats the difference between a retail processor and an unboxed / oem processor? im guessing the retail will never have been used, and the unboxed 'may', or most likely, have been used. will that matter much if im just trying to save a buck?
