Hi, I already havr Sapphire Tri-X OC R9 290X 4GB card. I am planning to increase the capability. My budget is around 350. I am considering two options, adding another sapphire R9 290X in cross fire, or selling my existing R9 290X and buy a single GTX 980 card. What you recommend. I am not a fanboy of any card, and Geforce exclusive features TXAA, Physx are not issues for me. I need better gameplay and I play at 1440p in a 32 inch single monitor with refresh rate max 60. My processor is pretty decent, Xeon E3 1245 V3, and 16GB DDR3 Ram. So they should not be a bottleneck in running latest games.
