Yes buddy, lpx are low profile sticks so fit perfectly with DRP3.
for me 1070 ti is very real and is coming very soon. I know nvidia only makes TI versions of 80,50s but they dont have anything "fresh" for fall and christmas market this year so 1070 ti is a desperate way to have sales and confront Amd vega. So wait for some days and we will see. (for now the tiny v3900 does the work)
Looks awesome, i wonder what case fans are you using? I dont see that in part list. Thanks.
