Should I install now or wait for a 10.5.7 release?

[Gerontius]

I have a computer with following specs:

 

Intel C2D E8400

Gigabyte EP45 DS4 motherboard

Gigabyte ATI HD4870 512MB video card

4 GB of RAM

 

I'd like to install OSX, but i know that current releases don't fully support HD4870. However OSX 10.5.7 will support it, and netkas and others guys have managed to use kernel extensions from that release with 10.5.6

 

So... should i wait for a 10.5.7 release, or install 10.5.6 now and install those kexts (it seems that it's kinda complicated)

 

Thx
