eMachines t6212 is alright, you don't need that much. Upgrading the machine would make your pc into a video machine. The Intel Pentium 4 is better at video editing, but you're not doing mass video editing, so amd will be alright and will provide you expandability into 64-bit.

I recently bought a digital camcorder and a digital camera - both of which have pushed me to get out of my 5 yr old Dell PC. I don't expect to do much (or any!) gaming, but will be burning DVDs from my mini-DV tapes and old VHS. Besides, the usual MS Office applications for light home use.
After some research, I believe I need 1GB Ram, a 3.0GHz speed chip, DVD +/- RW, 200GB HDD. And, I am fixated on having A/V inputs to connect the VCR directly to the PC, rather than through another device like Dazzle .
So, my questions are:
a. Any comments on the configuration?
b. Do I need to be obssessed with the A/V inputs - this has really limited the PCs I can select.
c. Any alternatives I should consider to the m7060n without paying too much more?
Thanks....after months of analysis paralysis, I am ready to buy...I think!
