You really only need the SAME model (i.e. R9-270X). You should however:
a) have similar GPU frequency
b) have same VRAM amount

The XFX models appear to be either 1.1GHz or 1.0GHz so just get one that matches that (and 2GB I assume).

Other:
I really dislike Crossfire in general as it still has issues. An R9-270X will cost you at least $220. If you want more performance my advice would be to SELL your current card (probably the best time since they're out of stock) and put that $400 or more towards a good SINGLE CARD. For a little more than that you can find the EVGA GTX780 (967MHz model recommended) for $490 after rebate.

FRAME RATES are only one factor. While Crossfire is improving, online tests can be deceiving. First of all, the DRIVERS need to be optimized per game usually to prevent issues and most tests are on recent games.

DX9 is still not working last time I checked, which ends up causing games like Half-Life 2 to report 60FPS but only show 30FPS (30 frames per second). You can Google the Crossfire DX9 "runt frame" issue if you'd like.

thanks and I agree that a single card setup would probably be the way to go but im looking for the challenge lol and honestly the single 270x works great for what i do but i plan on running 3 monitors thought would a single card still be the better choice then... I have alot more fun tinkering and tuning than actually playing with my set up but Im just getting my feet wet so i don't want to buy super expensive smoke bombs when i push to hard lol

you should wait a couple weeks or even a month before you buy a graphics card though, the prices are higher than they should be. bit mining or something like that.
