IB CPU's ain't much for overclocking ...have thermal issues. If going w/ big OC's Id get a 2500k
670 is great card....look for one with at least an 8 phase VRM design if overclocking, Asus DCII TOP, EVGA FTW for example.
Mushkin Chronos Deluxe is fastest available and made using toshiba premium toggle flash for extreme long life and is a steal at $119 ....which is what some 64 GB model's cost .... Unless you are astute windows user, 64 GB will be filled with e-mails, temp files, dmp files, common files etc within months.
