Which one is better? Also which one drains which power? As I will be trying to get one off of ebay in a month or so and was wondering which one would be the better of the two. I will be trying for a 512MB model.
the 8800GT will be fine on a 400w PSU. i ran it off a good 305w unit.
ATI had the 4830 to compete against the 8800GT/9800GT (same card) and the 3870 offered Nvidia 9600GT performance. All these cards are fairly old in video card years so the modern ATI 5670 would be the closest competitor to the Nvidia 8800GT.
I heard it improves performance by a bit? I have an HD4200 on my motherboard right now. So the 4830 doesn't support hybrid crossfire with my 4200? I got a micro-atx board so normal Cfire is not an option.
it doesn't improve performance, it shuts down your video card and uses integrated graphics (your 4200) for basic video tasks. For more intensive tasks it uses the video card. kind of like a hybrid car with an electric motor and gas engine.
its purpose is it save energy...it does it....not that your video card uses a ton of energy to display web sites.
