So I missed out on a supposedly excellent deal involving the Sapphire Nitro R9 Fury Tri-X for $300 (I woke up right after they ran out of stock), and I feel kinda bummed because of it. This whole time I have be waiting to get the Sapphire Nitro RX 480, but the R9 Fury line is considered the top cards from AMD at this time until the Vegas roll out around next year, and I could have gotten one. I'm only kinda bummed out because while performance-wise, the R9 Fury beats the RX 480 by quite a bit, it is limited to 4GB because the RAM type (HBM 1.0), putting a damper in it being future-proof. It also needs a much stronger PSU by comparison too, as I believe is missing some improved features like 4K@60 encoding. If I had the opportunity to get a R9 Fury for that price again, I don't know whether I would make the jump. What would you choose between the two, and why?
