Is it worth upgrading to the R9 290 trix OC

I recently just upgrade my motherboard and cpu. And I was wondering what is the next best part to upgrade so that my rig bottlenecks less than it is now.
Current build: -CPU: AMD FX 8370 OC'D @ 4.5ghz Mobo: Asus m5a99 pro -GFX: Sapphire R9 280x -Power supply: 750 watt M -Cooler: 212 plus from cool master -RAM: Ballistix 8gb sport DDR3-1600

But I was wondering if it was worth upgrading from my R9 280x

A small amount of time spent tweaking the settings on that 280x will normally bring you close to the same performance as the 290, so no, for the money spent isn't worth the upgrade. A 290x, yes, a 290, no.

I was thinking of going with this card

That would be a worthwhile upgrade from a 280x.
