Which PC is better for HD Video Editing?

I am looking at a Gateway FX6840-15e with Intel i7-870 4 core processor and a HP HPE-410 with a 6 core AMD x6.



I heard that the i7 is more powerful even with less cores, but I want to know for sure.



I want to smoothly edit HD video in programs like Sony Vegas Pro 10. 1080p if possible?

HP HPE-410: http://www.bestbuy.com/site/HP+-+Pavilion+Elite+Desktop+/+AMD+Phenom%26%23153%3B+II+X6+Processor+/+8GB+Memory+/+1TB+Hard+Drive/1243773.p?id=1218242847655&skuId=1243773&st=410y&cp=1&lp=1



Can you tell me the difference between the two processors and the video cards, etc and which would be suited better for HD 1080p editing without any lag?



Also, anyone know the max RAM the Gateway supports?



Thanks for any help!|||In general, video editing benefits from more physical cores... So an X6 is usually better (which one does the HP have... a 1055T, 1075 or 1090T?)



Here's the head-to-head comparison. While the Core i7 is much better for most applications, when it comes to video related tasks, the X6 is very close, usually with a slight lead.

The Gateway model can only have 8GB RAM, the AMD one can have 16GB.



Also, you may like to give Ubuntu 10.10 for AMD64 a try, it comes with Pitivi video editor, you can have more editors installed.



AMD combo will definitely be much faster, will give you better quality, performance and overall compatibility.



Also, since you are mostly concerned about editing videos in 1080p why not get a mac?|||With this converter, you can also convert videos for video editing software like Adobe Premiere, Windows Movie Maker, Sony Vegas, and upload video to YouTube and MySpace to share videos.
