The second one looks better since you only changed the GPU&PSU and the GTX460 is better then the HD5770.If you plan to add a HDD to your build i would reccomend the Spinpoint F3 if it fits your budget. The i3-530 is the best CPU you can get for the money but you can also look into Core 2 Duo E7500 & Phenom II X3 720 Black Edition if you want to go for a AMD setup or another Intel choice.
