Id go with the second build. Go with an HDD and a smaller SSD if you really want one. That 7850 on the other build is generally a better card than the 560Ti. How much editing and multitasking will you do? If not alot just go with an i5 3570K.
im starting a youtube channel, and im also editing som clips for freinds. so i will not say alot. but, some yes. lets say around 2- 10 min HD clips. 2 a week maybe 1. also. a smaler SSD like 120? or?.
