It all began with the Radeon HD 7790. AMD was preparing a new Graphics Card that equipped a Bonaire Core with 896 Shader Processing Units and that NVIDIA would launch a Second Revision of their GeForce GTX 650 Ti Boost Edition.
However, in the end, GeForce GTX 650 Ti Boost Edition seemed to surpass the Radeon HD 7790 and performed a fraction above the Radeon HD 7850. Adding to that, it launched at 169 USD, meaning it costed the same, if not less than AMD's Radeon HD 7850.
How cruel is that? AMD's Radeon HD 7850, last year, won the GD award for the most competitive Graphics Card/Best Graphics Card, considering a price/performance ratio.
Now, NVIDIA answers with the GeForce GTX 650 Ti Boost Edition. An even better Card with an identical price to the HD 7850.
As if that wasn't enough, a solution of two GeForce GTX 650 Ti Boost Edition, in SLI, offers superior performance to a single GeForce GTX 680! Not a surprise, considering the two Kepler GK106 Cores put together offer 1536 Shader Processing Units, 128 TMUs and 48 ROPs, on a 384-bit of fast GDDR5. The central unit runs at 980MHz and goes up to 1033MHz in Turbo Mode. This means, more bandwidth (and thus more ROPs) and equivalent "processing power", compared to GeForce GTX 680.
Needless to say this is trouble for own NVIDIA since it's much cheaper to get a solution of GeForce GTX 650 Ti Boost Edition in SLI, over a single GeForce GTX 680.
Sales for the Radeon HD 7790 were low despite the 149 USD release price. Its performance was a significant amount lower than the Radeon HD 7850, which made it less desirable. So seeing as performance differences were out of the picture the only reason to pick up the HD 7790 over the HD 7770 would be to run games at 1980x1080, as the HD 7770 was best suited for 1680x1050, a less common resolution.
The Radeon HD 7850 is still an extremely competitive Graphics Card but it feels that the GPU to beat at the moment is now the GeForce GTX 650 Ti Boost Edition.
Lets take a look at the relative performance & price of the mentioned Graphics Cards and ultimately, a price to performance ratio, which indicates the best deal. Of course prices can fluctuate region to region and you need to pick the best choice for you and your own setup, but use the following data as a good indicator.
