Hello, I just sold my 1.8 G5 on ebay to buy the dualie. However, I sold it with the 1gb of ram I had just ordered. It arrived today and I thought I would do a little test. I chose 56 pictures and added the ken burns effect. The duration was at 4:26 and the zoon was at 1.16. The G5 with 512mb of ram finished rendering this in 576 seconds (9m 36s). The G5 with 1.5gb of ram finished it in 448 seconds (7m 28s). I just thought I would share that with you. That is about a 22.3% time decrease! Not too bad!!
