    is it safe to get nVidia GPU thinkpads?

    Because the quadro 140M is basically the same thing as a 8400gs w/ upgrades, will i have any future issues?

    I want to use this thing for 4 years minimum.

    Future issues with what? It will still work 4 years from now just as 4 year old laptops work fine today.

    It just depends on what you're using it for.

    wasn't there a big issue with nVidia GPUs?

    If this for school and you have the time to wait, try to get the new T series later this year with the ATI + Intel dual graphics system. If not, the 140M should be fine. My card usually goes to about 75C on heavy gaming which isn't too bad but could be better

    I have a T61p and it seems fine to me, but yeah there was some news earlier that the video cards are defective.

    Same here. My FX 570M doesn't get hotter than ~75 °C (on a desk with an ambient temperature of ~25 °C) under full load.
    Seems like a reasonable operating temperature, no?

    For comparison, my T60's ATI X1400 never exceeds 65C under load and using Thinkpad Fan Control Smart Mode. Idle is around 53C at ambient temp.

    (That was a 1-hour AVI to mp4 video encoding session last night, which, I'm not sure how taxing that is. Not a gamer, sorry.)

    How taxing? Nothing. I think that most video encoder are CPU accelerated and does not depend on GPU.

    It could also depend slightly on form factor, 15.4" may be more efficient at cooler.

    As I've had both the X1400 and the 570M, the X1400 has much worse graphics performance so I'd take the higher heat tradeoff.

    One thing to keep in mind about the defective nVidia chips is not *only* how hot your card gets (although that is a factor), but the how often it gets hot and goes through the hot-cold-hot-cold heat cycle. That's what's really causing the material around the chip to fail. So if you go very often from heavy gaming to leaving the laptop to idle/turning it off, it might present a problem in the long-term.

    So should I get a doctor's note saying that I need to game 24/7 or else my GPU is going to fail? :D

    Everything is fine. Rumours fly fast. Don't worry.
