If you build it for cracking passwords with Hashcat, then no. 4x R9 270 (no X, right?) give a similiar performance like 2x R9 280X, while being more expensive and more difficult to handle (space, heat, power). The R270 is a 2-slot-card, so four of them won't fit on that particular mainboard, which btw. only supports PCI-E 2.0 instead of 3.0 -slots. The CPU and mainboard are together way too expensive, compared to some average Intel-Mainboard and CPU (which should cost 2/3 and offer PCI-E 3.0). The power of that CPU is simply wasted for Hashcat.
My advice: get a decent Intel Mainboard with two fully powered PCI-E 3.0x16 slots, a nice Dualcore and stuff the saved money into a R280X. You'll get 70-80% more performance in Hashcat compared to your original setup.
For every other purpose: I can't tell. Depends on what you wanna do with it. But if it involves gaming, same as above. Too much money into CPU/mainboard and way too less into the graphics compartment.
