- Why do you want to upgrade, not enough performance or what?

That 750w should just fit two R9 280X's but with not much to spare

If you do go for 2 280X's, get an i7 at the same time.

Why do you want the i7 4771 over the 4770k?

Also, I'd get 1x 4TB HDD unless you want RAID or something

Have you overclcoked your cpu?

Your PSU will be fine for a second GPU and if you did upgrade to a i7 cpu but I would try and overclock.
