Hi! I'm building a cheap pc (with a fx 8120 and 8gb of ram) for video editing. I just want to do basic editting with sony vegas using videos at 720p and 1080p (videos of 10 or 15 minutes). But I don't know which graphic card i should buy.
Your cpu will bottleneck any Vega GPU. You need to get an updated processor to handle them. You would also want either 16 or 32 GB of RAM as well for your editing.
