Basically NVIDIA physically rob people by:
- Trying to force you to match cards for SLI.
- Only allow you to connect two monitors into each card rather than three.
- Giving you really crap default VRAM for today's standards.
(I'm sure we can add more to this list)
The sole reason that I'm stuck with NVIDIA, sadly, is 3D Vision. Otherwise, nothing but a middle finger to the capitalist pigs!
I prefer Nvidia despite all this, TDRs aside, Nvidia has better drivers than ATI, and ATI/AMDs upper level tech support were complete dicks to me when I tried to educate their tech on why their OpenGL drivers could only make 1 call in the time that Nvidia could pump out two(almost three).
If you want a fast example, try an AMD card versus an Nvidia at the same relative "power" in any direct3D/DirectX type game, and then compare them both on an openGL game. AMD's cards will do, say, 60 fps with a minimum of 24, where as the Nvidia will be slamming at 170 FPS with a minimum of 45 FPS. ( Second Life, KOTOR, KOTOR 2, so on and so forth.)
In fact, KOTOR went on being unplayable on AMD/ATI cards for nearly a half year. That is really sluggish.
Edit; to further explain. AMD/ATI has a CAD/graphics designer line of cards called fireGL. FireGL cards have a huge price tag, AMD wants professional studios to buy the high priced cards. The only way they could do it, here lately, is by purposely hamstringing the openGL instruction sets. OpenGL, by the by, is what most of the CAD and 3D design software is made in.
AMD normal < Nvidia normal < FireGL.
You can think of it as if you had to figure out the answer to a common long division problem, versus knowing it out of memory. Nvidia's normal line of cards has more time saving computations already figured out and baked in.Edited by Gerick - 1/25/12 at 4:43pm
