I currently have a ASUS P5RD1-V Pentium 4 3.0 4 gb mem, hd 750 gb Windows 7 ultimate.
It is a little bit slow and would like to upgrade for Video Editing. any suggestions on the road to take about upgrading?
Pentium 4 670 @ 3.8Ghz is the top CPU that would fit in that motherboard.
There is really no good upgrade path for your motherboard.
No dual or quad core CPU options available which is what you want for video editing.
