basically saying which do you think looks the nicest, that's basically the only diff between them really other than the 20mhz as he pointed out, but as he said you can overclock it past that in a heartbeat.
Thanks for clearing that up jonnyp11. Sorry if that was not all that clear.

Go with MSI or ASUS. I am partial to the MSI cooler since I have used it before and I know it is a great performer. The 20MHz that you would need to OC in order to get it to 900MHz is not hard at all. I would bet you could have it OCed and tested stable in no time.
It is up to you what card you want but that is just my opinion.
