Positives:
+ Unlike NVIDIA, which mainly optimize their consumer cards for games / players, you are in AMD even faster with this card as a price equal NVIDIA cards (google: "AMD NVIDIA OpenCL benchmarks")
+ AMD's hardware is here, so to speak openly and provides better OpenCL support (NVIDIA one is dependent on the proprietary CUDA and NVIDIA is said to have set the OpenCL support all)
+ Better mining / Cryptography Performance (but brings NVIDIA's 750 Ti Maxwell architecture map here strongly on: scaled to the 750Ti order to compare them with this card can (because there is no faster Maxwell tickets, but soon), the 750Ti would 27 % faster with the same wattage:
Once upon cores scales: 640cores = 52kH / s; 2048cores = 166kH / s (280X the only 130kH / s creates)
Once upon wattage scaled: 60Watt = 52kH / s; 250W = 216kH / s (the 280X also here more consumed (250W))
That is, if a Maxwell 250W card comes out, this might the 200kH / s (independently of the first of which kH / s is talking about)
PS: should now someone will come up with the idea with this video card (or generally with graphics cards) any bitcoins to mines, should be mentioned here that since you ASICs can buy for graphics cards for this work are far too slow / expensive and therefore obsolete (because graphics card are a bit like FPGAs, so can be programmed for many Cryptos, are therefore but no crypto hardware optimized, while an ASIC is for a particular crypto, but even for this, hardware optimized).
