I'm getting back into home editing (on AVCHD) and buying a new PC for the purpose. The choice at my price point is between a Quad-core Q8300 processor and a more powerful but more expensive i5-750 - either with 4gb of RAM and twin 500gb hard drives. Graphics card would be modest - something like a Geforce GT220 or 240.

Is anyone out there successfully cutting AVCHD on a Q8300/4gb system? If that's all it will take I'm reluctant to spend the extra on an i5.

Software-wise I'm thinking of Premiere Elements on the grounds that it should be friendly enough for my son to use, too. At work I've been using Avid Xpress for many years and I've used Liquid in the past at home for standard-def DV.

Grateful for any pointers.
