That's a rather silly assumption on your part. A good number of us as OC'd, most on air, and I've helped many OC as have others.
True statement, I did make an assumption. I would not say silly tho. Many folks do consider OC'ing a none starter. Not worth the possible consequences. For me it was part of the learning process. I bought the 920 DO, it was meant to OC. Read a lot of crap when researching the components. Same reason I RAID'ed my SSD's. Learned about RAID usage and SSD's at same time. If I could only wrap my brain around writing software..............

Tinkles, You OC to save dollars, IMO. I paid $286 for the i7 2.67GHz cpu. By pushing it to 4GHz, I got $1200 worth of performance. Around $1200 was what an i7 965 at 3.8GHz cost when I built this machine.
Once you get things together, use the new machine awhile. You very well might change your mind about OC'ing. Not saying you will, but its part of the knowledge progression. Knowledge is power, once you get it you want to use it and get more knowledge. If I was to start another build in future, and I prolly will. I would put a floppy in it if the mobo had a header for it. It just to easy and cheap. Obsolete or not.
Maybe its just me. I have been building things my whole life. Working as a builder/installer of stage plays, I have been exposed to a wide variety of materials and techniques. Wood, metal, plastics, fabrics, electronics, welding, woodworking, sewing, overhead rigging, machinery, it all same to me. I even build my own flight gear for the game. stick, peddles, throttle. I'm a master of nothing, but pretty dam good at everything.
When given a task, I learn what's needed to accomplish that task, then accomplish it. Building computers is no different.
Similar to a safe landing, its all in the approach.

good luck with you new machine.
