Haven't swum in the intel pool for a long time, and I'm getting my a' kicked by the number of sockets/chipset we'll leave out 775/1150/1151/1156/2011 cause I've already bought 2 1155's. So that makes it "simple" the 1155 socket and pick a chipset from..
B65/H61/Q67/H67/P67/Z68/B75/Q75/Q77/H77/Z75/Z77...
Holy shnikies Batman!! Intel makes more kinda chips than Doritos!!!
So my first mistake was buying an H77 board (ECS X77H2-A3 V1.2) not realizing it was locked down multiplier and pretty much the exact wrong choice for a i5-2500k. Also the jedi mind trick of "X77H2" X=Performance right? Who cares if there is no X77 chipset, the X looks goood...
My second screw-up???
Asus P8H61-M LE R2.0 now I checked the manual this time, and by the EXTENSIVE overclocking section it seemed like a good oc board (ok it was board #2 & it was cheap) but roaming the interwebs it the sentiment is this chipset is no bueno for overclocking?
So my options ECS X77H2-A3 V1.2 i5-2500k (in hand) no oc, but 4x4gb ram, or wait for the Asus P8H61-M LE R2.0 (shipped today) and oc'ing??? but with only 2x4gb ram.. /Edit option 3 sell both and start from scratch, uuhhg..
