Comment: ATI problems and alternatives (Score 1) 165
Performance wise, the HD 6670 is not exactly a high end GPU. I have one myself and it is OK for most games, but then I don't expect to run my games at maximum graphics settings. If you expect high quality graphics with decent FPS, a 6850 would be the minimum. Or maybe a HD 7770.
Second, I can confirm some funny artifacts under Windows (windows switched to the background are not fully overwritten). This happens both with the HD 6670 @home and the HD 5770 @work, so I suspect a driver problem that is common to the 5xxx and the 6xxx series.
This begs the question: what is a good stable video card that can give modern games under Windows an enjoyable experience and also provides a solid experience under Linux with preferably an open source driver?
Right now, there is no perfect solution, only tradeoffs:
- If you have plenty of money and are willing to live with a closed source (but having a good rep) driver under Linux, the Nvidia GTX 670 looks good. But their midrange Kepler stuff is not released yet. The older Fermi "Thermi" models get clobbered on performance per watt by AMD.
- If you insist on open source drivers under Linux, you are stuck with AMD for serious graphics cards. But the open source AMD drivers under Linux suck at performance.
- For those who don't have big GPU performance expectations, Intel is becoming interesting with the HD 4000 integrated graphics. But it still gets clobbered by the HD 5570, see http://www.anandtech.com/show/5771/the-intel-ivy-bridge-core-i7-3770k-review. So even Intel's best integrated GPU still loses to a discrete lowish-end card
