If you buy the I7 and regret spending that extra cash, that would also suck. But you can always say "well... sure it have cost more than i would have liked, but atleast i have the best of the best for the 1150 platform"
Touche! I mean, before long I am getting an awesome job at a company as a Mechanical Engineer because I'm going to be doing an apprenticeship through them. So, living alone, and coming home with a health paycheck, I'll be building a badass rig once I get enough money to do it again.
