8GB of RAM will cover you just fine and if budget permits I would suggest getting two fast and cheap 7200RPM drives for RAID0 to use as swap during producing and at least one other drive for OS and data.
I play occasionally with PowerDirector9 to do my home videos from BluRay camera AVCHD1080 and editing of large files is much better after I moved to 8GB RAM even though app itself isn't allocating too much of it.
Editing everything from one drive was painful at times where once I moved temp. and preview files to RAID0 of 2x1TB SammysF1 while keeping original material on another single 1TB Sammy helped a lot during production process.
My rig runs OS from SSD drive which is ideal solution but if on budget skipping it shouldn't affect overlay performance too much for you.
Here is an example of PD9 at work. Whole material was over 2 hours and took me 3 hours to produce the whole thing. Mostly deciding what to cut out and adding subtitles.
Back then on Phenom X6 3.6GHz I did all of that quite comfortable without any 'waiting' for computer to perform task required. Producing final material took about the same time as resulting video on that CPU.
Good luck with your build and have fun making videos![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
