Anyway, I've been considering an upgrade sometime this year from my 6550D (on r600g) to probably the R7 260X. Based on recent benchmarks it doesn't look as though that upgrade will gain me much just yet. Maybe in 6 months either radeonsi or nouveau will be on par with the quality of r600g and I'll make my choice then.
No announcement yet.
