How does video graphics card power consumption differ?
So, I own a Nvidia GeForce 9400GT graphics card and I want to buy a new one in May 2010(I want to spend around 200$-250$). The question is, if i will buy a pretty new(as in date of release) and highly performant graphics card, will there be any difference in the power consumption/voltage for the card itself? I mean, will I have to change the power block for my computer in order for my graphics card to run at maximum efficiency? I'm not sure how these things work.

Yes, if you want more performance you need more power. It uses the extra power to fuel its improved performance. The universal logic: More input, more output works here.
Since the power demands are increased you need a PSU that can support. You'd be using a 400-500W rated PSU for the 8400. But if you're buying something more powerful, say GTX 280 or HD4870, you surely need an 850W or 1000W rated PSU

Yes. A high-performance video card typically requires much more power than a low-end video card

The truth is, maybe. It's hard to say as to what graphics card you have, along with what your power supply is currently rated at. Something you should also take into consideration, power supplies slowly lose their capacity.
