PC upgrade help

[xy23po]

Hello, i was looking to upgrade my pc without having to spend money on a new psu. Here are my specs:
Gigabyte 970A motherboard
amd fx-8320
Astek 510LC Liquid Cooling
amd r9 270 2gb msi gaming edition
8gb ddr3 1866Mhz ADATA XPG V2 Ram
600w psu

I was planning to buy a R9 270x but i have about a $175 budget and that is too expensive. So i looked and i found a R7 260x msi 2gb edition which i can crossfire with my r9 270.

I want to know if i need to get a new psu if recommended and if it is worth it to buy the 260x.
I am not looking for future proofing, just something that will fit my budget. If there is another option then please tell me. Thanks!

You're probably not to crossfire any card worth putting into crossfire with a 600W PSU.
Plus, you shouldn't be running two cards in crossfire if they're under $200.

I recommend you should just overclock your R9 270 to the R9 270X, and just settle with that until you get about $400, then you can get a more major, substantial upgrade.

Here's the sort of thing you would get for $400. (talking single-GPU solutions)
If your 600W PSU is already a quality one, let's say a XFX or Seasonic/Antec unit, then you're set, spend it all on a beastly GPU.
But if not, and it's a non-branded or bad quality unit, (example CX600, CS600 etc.) then you're going to need to spend some money on a quality Supply.

Corsair, Evga, Seasonic, or XFX are great psu's, and you would need at lest a 650W
