Kind of a late reply but... this is my current system:
--Dell 24" Wide Screen LCD
--Antec P180 case
--Logitech Wireless Mouse and Keyboard combo
--Windows Vista Ultimate
--AMD Athlon64 X2 4800+
--2GB PC3200 DDR Ram
--1 TB total HDD space, 500 GB of which are in RAID 1
--ATI Radeon x850 Pro AGP Graphics Card
--Maddog 16x dual layer DVD burner
--Sound Blaster X-Fi Xtreme Gamer
No videos have yet been made on this system. -_-
My first two videos were edited on a much, much slower system (AMD 1800+) with 512MB of ram, using a crappy CRT monitor, and a 20GB hard drive for storage.
