Wow, the Radeon 5570 takes 45 watts, and the Quadro FX 3400 around 350 watts!!! No wonder why it runs so hot (and noisy too).
EDIT: that's wrong, but, no other stupid sites would tell me the exact power consumption of the FX 3400.
EDIT: it's 101 watts, thanks wikipedia.
That's one power hungry sucker. I think I may get a Radeon 5570; I've never been a big Nvidia fan anyways. Plus I could free up a lot of power for other things. Not to mention, the quadro fx 3400 is so long.
The Radeon 5570 doesn't seem too expensive, and it's an older card too.
Look, I hate the power consumption, heat and noise nvidia cards produce as much as the next guy, yet I still prefer them for their drivers.
As far as I know, they are still the only ones with a performant/complete OpenGL implementation and games for Linux support.
Also, Quadro's are optimized for graphical design. Hardware has progressed a lot in those 5 years since your card was released, but keep in mind that the consumer ATIs are optimized for gaming where you want a high FPS instead of a reliable display of all parts in your design.
