Psychosaysdie,
While I agree that it may not be the best tool for stability, it will point issues in your setup.
Personal example: I had a buddy setup a system, overclock, and just played games right away and was apparently stable. After awhile he would complain about his computer crashing apparently randomly between 1 minute and 1 hr after startup, and he didn't due as well on benchmarks with people with nearly the same exact system.
I ran Prime95 on his system, and at least 1/4 of the workers failed within second of starting the test. Eventually his system would just crash; hardly stable. We tweaked the bclk, RAM timings, and voltages and eventually got where he could run Prime95 for 24 hr no problem, Intelburn test 10 runs, too. Now he runs games like a champ, has his system on for weeks at a time with no crashing, and his benchmarks are where they are supposed to be.
Like I said it's not the best, but at least with Prime95 you can repeatibly test your system for stability instead of waiting up to an hour for your system to crash.
To the OP, I hate to say 'overclocking an i7 is easy', but there are a lot of guides you can find online by going to Google and type 'overclock Intel Core i7 930' and compared to the older AMD and Intel chips I've worked with it is much easier.
You will need an aftermarket cooler, a good application of TIM/heatsink+fan, and time. Eventually after adjusting your voltages and clocks appropriately, you will reach the point where you are as fast as you want to be and running as cool as you like.
