Im stuck between deciding if I should get the E8500 or save $20 and get the E8400 and OC them... Thing is, I DONT KNOW HOW TO OC!!!!

Where do I go/What do I do to learn how to overclock and will this shorten the life span of my computer?

I'd like to have it @ 3.3-3.5GHz

If you just want a 3.5 GHz OC on a Duo, then save yourself some money and get the E7400/E7500 instead.

Have a look at the Overclocking Forum at TH. At the top there should be 2 stickies, the Temperature Guide and the How to OC guide.

Stay below 1.3625V for vCore and you should be OK.

A stock E8500 is a pretty fast chip, but also easy to overclock. If you are unsure about overclocking, you could just get it and run it at stock speeds. Another factor is that if you want stock speeds, you can keep the stock cooler. To overclock you really need a better cooler and that will add around $40 more.

so, you already have aftermarket cooling. so there will be no problem getting your pc to 3.6 ghz.

For your comparison : my e8400 running at 4,2 ghz (add 0.1v to v-core voltage) with xigmatek 1283 cooler, and it ran stable so far

Are there any video's that explain how to OC?

i dunno about video, try youtube maybe. but it's not as hard..... the point is, if you are using c2d, then just change your cpu fsb in bios, my default e8400 is 333 x 9 (9 is the multiplier) so 333 x 9 = 3ghz. try changing it to 400 for exxample, so it become 9x400=3.6 ghz. just leave other setting alone for now, try stress test your cpu, if it become unstable (hung app, instant restart, or blue screen) then the next step is change your v-core voltage, with my e8400 i add 0.1 v.
and you dont mention your ram.... so i can't tell you how to tweak it so your ram not bottlenecking your o'c. and in my bios setting the pci-e clock is set to fix-100.... otherwise it's possible that your pci-e clock is accidentally go higher that could damage your gpu.
