The i5 will be better for gaming, and the xeon will be better for video editing. So you now have a problem. All i can really suggest is if you are going to be doing more gaming than video editing, go with the i5. if you are going to be doing more video editing than gaming, go with the xeon
Thanks looks like I will be going with the Xeon. Will it outperform my AMD phenom ii 960t in gaming?
