So I have a eyefinity setup of three monitors running at 4800x900. I was wondering if it would be better to have a crossfire setup with the 7870GE or will I be better off getting say a R9 280X card. I biggest thing that I have an issue with is I don't really want to spend $300+ for a new card when I can get a 7870GE for $179.
My current rig:
AMD Phenom II X4 955
GIGABYTE GA-970A-D3*
12 GB RAM
XFX Double D FX-787A-CDFC
OCZ Fatal1ty 550W*

* I plan on upgrading these
