Safari Won't Stop Crashing...

I just wanted to put in a side note that Safari crashes a little too much for my liking. It usually happens when I am trading stocks or doing something really important. Maybe the can fix this with the new release. I keep feeling that the memory I have on this iMac just isn't enough.

I have a G5 with a ton of memory but ever since I installed the new OS and latest iLife things have not been so good. I have not had time to really dig deep into why both of my macs are crashing a lot these days...
