    with this power consumption, i think 7970 is cheaper than you think it is...

      And don't forget, Kepler will arrive soon with full GNU/Linux support.
      I only count Open-Source drivers for Linux!

      This means Nvidia is upper shit for Linux!

        The 7970 is expected to be around 575$

        GTX590 is dual GPU, which means most games will not achieve optimal performance, some cases even less than 50% optimal performance
        7970 is single GPU which will get optimal performance in almost all games.

        Cheaper product.
        Consistent product.
        "Energy efficient" product.
        There is great value in this card if you're a bleeding edge kind of guy.

        Personally, I'm a bang for buck kind of guy.
        And I really like the HD7970 even if I'll never own one, because after its announcement, the 6870 went on sale.
        I spend 200$ every 2-3 years on a new GPU.
        This year, it got me from a HD4850 to a HD6870.
        I was still up to date before, and now even more so.
        I can play all my games on very decent to max quality @ ~67$ a year; whereas buying a new bleeding edge card every year would average roughly 400$ a year.

        But that's just me.



        Now I'm waiting for the prices of SSD's go down. I'm hoping that next fall they will start averaging less than 1$ per GB.

          I'm tired of fanatics.

          But since you only use open source drivers, I expect you to not use EFI or any proprietary firmware, since these are also "evil".

          Please tell me what's wrong with the nVidia drivers? Yes they are proprietary, free software is always preferable, but seriously, how does this driver restrict your usage of the system? Please answer like a grownup, not like a three-year-old. The nVidia drivers are not evil, they utilize open protocols, custom hardware APIs, and even the display settings are open source. The remaining proprietary piece is the "binary blob" mainly due to different technologies nVidia has licensed from third parties.

          nVidia offers enterprise quality drivers, with good OpenGL support, great stability, good power management, great video acceleration, performance on par with Windows (incl. Direct3D) and more. The open source drivers has very limited features and performance compared to the proprietary ones, and in reality you'll end up with a high-end card performing like a low-end card (proprietary drivers).

          Personally, I would say drivers without proper support for modern OpenGL specifications does not count! And as a graphics developer, I would say the open source drivers are a nightmare to work with. Drivers should behave according to specifications!

          But since you are on a rampage against everything proprietary, I expect you to fight against EFI. As you should know EFI uses proprietary PE-executables to load the OS, and the EFI "kernel" is technically capable to control every device on the system without the OS's awareness. Please tell me, which one of these two issues is the important one? To fight nVidia for proprietary "goodhearted" drivers would be like declaring war on your neighbor for not cutting down his tree during the second world war.

            You forget to say, that the opensource radeon-driver needs a firmware, which is not free nor open.

              If you only count truly free stuff, Intel is the way to go. Except for wifi cards and their firmware.

                You forgot to mention that hardware is not free or open either

                The microcode is part of the hardware, not part of the driver. The hardware docs describe the behavior of hardware with microcode loaded, and the driver is written against that behaviour. Some GPU vendors build microcode into the chip, others require that the microcode be loaded at power-up by BIOS or driver. I would argue that building microcode into the chip does not make it more free, it just lets you pretend it doesn't exist as long as you don't think about it too hard.

                Most CPUs have microcode as well; usually built into the hardware then patched by an image that gets loaded into a CAM by the OS.

                  That goes both ways, only a fanatic would like EFI. BIOS may be crap, but EFI is an even bigger crap. Luckily I haven't encountered any EFI motherboard for AMD CPU's yet. Also, AMD is a supporter of coreboot so I hope i will never have to use EFI.

                  My only experience with nVidia cards was about 6 years ago but i guess all the problems I had with the blob are still there:
                  - latest kernel or X server was never supported until several weeks later (not to mention using a rc kernel is out of the question)
                  - when rebuilding my own kernel I had to remember to rebuild the nVidia module (this is not necessarily a problem with binary drivers, but with out-of-tree drivers)
                  - the nVidia kernel module would taint the kernel making any bug report for a kernel bug worthless

                  If I wanted enterprise quality 3D drivers and didn't care about my freedom I would use Windows, really.

                  True, if you want latest OpenGL spec the free drivers are useless, but few graphics developers do, latest specs will only become important for most Phoronix readers in a few years when next-next-gen consoles will be launched so they will be widely used in games.

                  Not even Richard Stallman is against everything proprietary, that kind of fanaticism is only in your head. But, yes, proprietary drivers and EFI are evil.

                    The most annoying thing about the AMD cards firmware is that it's not included in the kernel tree, so when building the radeon KMS driver in the kernel image you need to also set CONFIG_EXTRA_FIRMWARE. If you solved this part the complaints about the binary firmware will mostly go away.

                      in the end its a kindergarden way of argumenation 1 is more than zero and 2 is more than 1 and 3 is more than 2 and so one and so one.

                      He really try to arguing in that way "hey your firmware is cloused source because of this your driver must be cloused source to"

                      i call it bullshit!

                      the cpu is the best example the firmware of my CPU is also cloused source and my opensource software "linux" work well.

                      in the same stupid logic i have to use windows "cloused source" because my CPU firmware is closed to.

                      and he call me a fanatic.

                        1. All known cards in the same Flops and generation have near equal D3D and OGL performance. Radeon has bad D3D to OGL translation, only 1/3 the Nvidia performance.
                        2. Benchmarks always lie. Nvidia GTX480 has almost 4Teraflops(32bitFmac). A Radeon6970 usually has 2,7Tflops(32bitMadd)=2.1Tflops(Fmac). Current Nvidia is faster than Radeon7000(3.7Tflops???).
                        3. Cuda has good programmability (Wine-Mediacoder) and runs C,C++,Java(C to Cuda) and more. Both have OpenCL (Nvidia even in G80), but OpenCL good apps ware??? Amd says C for Radeon7000 and
                        x86 memory addressing but we will see.
                        4. Radeon has bad compatibility, some games like CSS, hate Radeon and crass in DX9+ mode.
                        5. Nvidia is cheaper. I have a 100box new gtx460se. 288cores@1.8ghz(3.1Tflops) from the shop, and 336cores@1.9ghz(3.8Tflops) with other bios. I bay the same used, 60box for a friend.
                        6. Nvidia Kepler(GTX600) will have 400% performance per Watt against a GTX400-500. Half because 28nm and half because Kepler Cores are half the size of Fermi Cores.
                        7. Nvidia is the best choice for now. For Linux is the only choice.
                        8. Some tile based mobile cards (not tegra), have 300-500% performance per Watt and area, against the newest Kepler and Radeon7000, in the same lithography(28nm).

                          9. And as for Ray-tracing, only OpenRL has good graphics yields in order to be usable, actually has many times the raster graphics quality at the same Flops. Any way 2012 is the beginning of the end for DX11.

                              Nothing from the above. When I know something well, then I speak. If i don't, then i prefer to listen. I am not geek or hardcore, I am good in three things: martial arts, computers, harmonium, but not grate. If I have something good, is my critical ability. For example, I prefer systems like Zeitgeist over Capitalism and socialism, and I know why.
