In addition to the upcoming Radeon R7 260 and the revealed Radeon R7 265 graphics card, it appears that AMD is also working on the Radeon R9 280 as well, which should fit just nicely in the sub- US $300 market segment.
Still based on the Tahiti GPU, the R9 280 should pack the same specifications as the Radeon HD 7950 and pack 1792 Stream Processors, 112 TMUs, 32 ROPs and a 384-bit memory interface paired up with 3GB of GDDR5 memory. Since Tahiti is doing quite well these days, AMD might fix the GPU to work at over 800MHz while memory should end up at around 5.0GHz.
While the R9 280X is still considered as the US $299 graphics card, the R9 280 might hit the sweet spot somewhere below it. We guess that AMD might put it at around US $249 since there is a decent gap between the US $199 R9 270X and the US $299 R9 280X.
