Hi There,

I bought my video cards flashed as well on Ebay. It all has to do with availability by Apple.
You run a risk, but if you skim the web, you'll find out which brand and type is the best to look for. You can flash your cards yourself, or buy them on ebay.

We have 2 4870 with 512mb more memory then the standard cards. It's really worth the gamble.

Anyway, getting back to my first questions, I have installed 10.6.2 and I see 5 windows with 1080p clips looping flawless. no stuttering. with 10.6.5 I did 3.

Thanks Mr P!

cheers Michel
