Aluminum heatsink are better than nothing. I gather you will stick them to your VRAM with thermal tapes ? Of course it will also help if you have a side intake fan blowing air over your video card. It would help dissipate the heat faster from the heatsinks because it will move air away faster.
Copper has a thermal conductivity that's almost twice as better than Aluminum's so if you want better performance (and most likely the ability to push your video card's memory a bit higher) I'd say go with Copper heatsinks.
