I’d recommend Sony Vegas Pro 9.0. I’ve been very pleased with Vegas Pro. It’s quite versitile, not only for video, but audio as well. It’s a complete package, with many plug-ins, and the ability to burn Blu-Ray (assuming you have a Blu-Ray burner).
Since you have a 64-bit OS, you can install the 64-bit version of Vegas Pro, and access all of your 6 GB memory.
