47amir :
X99 motherboard (msi) + E5 1620 v3 + GTX 770 (msi) + 8GB ddr4 Ram
H97 motherboard (asus) + E3 1241 v3 + GTX 970/780 (PNY/zotac) + 16GB ddr3 ram
wich one? for AutoCAD & Gaming.
Be patient please. The X99 will have more upgrade options, I suggest getting the X99, with the E5 1620 V3, the GTX 970 and 16 GB of RAM.
HOWEVER, the H97 will be able to utilize the new up coming 5th generation intel cores, but I feel like when working with CAD the X99 is the better choice.
