Buy the ASUS end of. Why?
1- 5yr warranty on ASUS
2- Overclocks just as well if not better (due to higher spec components)
3- Comes with software that enables "fast charge"
4- Looks better
5- can flash BIOS using USP if you break it
Also, my recommendation regarding the rest of your PC specs:
- swap to an i5 3570K if you only plan on planing games or software that doesn't use multithreading or use multiple cores
- swap the PSU for something from Corsair, SeaSonic or XFX. These PSUs are MUCH better and more reliable. You don't want a "cheap" PSU taking out the rest of your components
-change to a 23"+ LCD.
Only saw now that you want to run Solid Edge, stick with the i7 then
