Benchmarks Real world tests of Radeon HD 7870 vs GeForce GTX 660

Passmark Industry standard benchmark for overall graphics card performance

3DMark 11, as the name might probably suggest, makes use of the Microsoft DirectX 11 API and puts every feature of it to use, creating astonishingly realistic visuals.

3DMark Vantage (Texture Fill) Industry standard benchmark that tests DirectX performance

3DMark 11, as the name might probably suggest, makes use of the Microsoft DirectX 11 API and puts every feature of it at its disposal to use, creating astonishingly realistic visuals.

Crysis: Warhead (2013) 1920x1080 - Enthusiast Quality + 4xAA

Radeon HD 7870
44.2 fps
GeForce GTX 660
39.6 fps
Since Crysis 2 is a multi-platform game with major development focus on the console, the graphics on launch day were only DirectX 9.

Batman: Arkham City 1920x1200 - Extreme quality + FXAA-HIGH

Batman: Arkham City uses the same Unreal Engine by Epic as Batman: Arkham Asylum, but it has, thanks to the engine's modularity, been overhauled and equipped with the latest technologies, including a graphics engine that takes advantage of DirectX 11.

This isn't just a game - it's a masterpiece - a very large sandbox game that rejects the quality-quantity inverse proportionality.

All AMD GPUs are seeing an increase in price due to supply and demand. People are buying them like crazy due to bitcoin mining.
7870ghz went from $150 to $250
The only problem is the 7870 will artifact 2-3 years later when AMD adjusts the catalyst drivers to make them artifact, They do this now with the 5000 series and older, to trick you into thinking you need a new card, But if you get the 660 2-3 years later you will be fine.
Only problem is amd will adjust the catalyst drivers 2-3 years from now to make the 7000 series cards artifact like they do withh all older cards to trick you into thinking it went bad, But if you buy the 660 2-3 years later it will be perfect.
The 7870 is not only a great deal cheaper, it matches and outperforms the 660ti and has exceptional overclocking abilities. It's a no-brainer. The 7870ghz, even though sporting the Pitcairn core, is the real gem of the 7-series. Best bang for the buck out there.
