One thing I like about the 520
The 520 sure is low wattage. That would lend itself better to passive cooling. The 430 is twice the Watts, which is still on the lower end of the middle of the spectrum as far as GPU power consumption goes. There can be a correlation between power consumption and performance with graphics cards. Apparently you don't get nothing for nothing even in the virtual world.
It makes sense though because I believe it is during state changes that the most power is consumed. So the more bits flipping on and off the more energy is required.
It is interesting to note that the 530 is almost double the 520 in just about every respect. What does seem to hamstring the 520 is it's memory bus bandwidth. All 64 bit cards lack in the performance area. Memory bandwidth is one of my red flags when looking at the plethora of video adapters on the market today. The power some of these devices can consume is not to be overlooked anymore though either. Not unless you have one of those hair drier power supplies. You know, like a Conair 1000 Watt model.
