[citation][nom]Benihana[/nom]Hard to think I got this excited about the Voodoo 3 back in the day. And one day in the future, this Titan will probably be out-powered by my car's onboard computer.Now to start booting up the ENIAC in my basement...[/citation]
I wouldn't be so sure about that. The very low end graphics markets have slowed performance improvement greatly compared to the high end since Voodoo was around. Titan and even some much slower cards might be faster than any car's on-board computer until we no longer have cars unless we find a reason to need more performance for that job.
For example, most of our lowest end graphics are still using the fairly old Radeon 5000 VLIW5 architecture or Nvidia's Fermi architecture and many even still use the same GPUs from the Ati Radeon 5000 series and Nvidia GTX 400 series. Then we look at a lot of the more mobile SoCs that are around and even weaker, yet these are what we see in more and more use in stuff such as cars. It seems that low power consumption and/or cost is a bigger driving force (with good reason) than higher performance.
I wouldn't be surprised to see stuff such as phones, tablets, and other low-power devices where performance is at least a little more important get like what you said, but even then, chances are that such devices will become more like thin clients for most people well before they reach Titan's performance.
