Yes you need to upgrade the power supply and pick another motherboard. You need a motherboard with 2 PCI-E X 16 lanes to run X fire at 8x8 that board has 1 X 16 and 1X4 this will gimp your Xfire.
You will be able to pull 400 Watts with just the processor and video cards the TDP of each card is 150 Watts then 95 for the processor with that your already drawing more watts than you need to with that power supply.
You should be looking for a quality power supply Seasonic, XFX, Rosewill Capstone, or EVGA G2 series in at least the 650 Watt range.
I'm not a fan of buying open box items the I/O shield could be missing but a board like this.

Good price on this power supply and will give you plenty of breathing room for overclocking.

Now i guess the next question would be is it worth my time to upgrade all this or just upgrade to a better GPU? I know my Mobo and PSU need upgraded anyways but to Crossfire 2x Radeon R9 270's worth it? or shoul i bump up to a 280

Yes your stuck in between. You will be spending a lot of money to Xfire 2 mid level cards, a 280 is not a good change it's not a big bump up form a 270 unless you can sell your card then buy, your power supply really cant handle a 290. I would think about selling your card upgrading the power supply and buying a 290 video card and keeping your motherboard.

Well judging by those benchmarks thats a substantial increase in performance not to mention ive been wanting to play Metro LL Redux with some better resolution :D. Now what about the 280x im looking at those benchmarks and those are even more amazing. But the wattage difference cant be that much can it?
