Each one of those chips have an unlocked multiplier (no FSB OC on these) so you can OC to the sky on any of them. The mainstream chips also have unlocked setups. 4690k, 4790k both unlocked. Honestly, if you don't video edit or transcode much on your PC I'd say just get yourself a 4790k and save bundles of cash or even the 4690k. Just as fast in gaming and will last pretty much just as long. APIs and such are moving more processing to the GPU to reduce CPU overhead and I'd say maybe in 10 years time a CPU won't be required much for gaming.
Yea this is my 3rd vehicle. I have a 99 Mustang GT that I paid cash for. 1 owner car, female, and babied. Interior basically perfect and had less than 110k miles. I can tell it wasn't abused because the trans shifts so quick, sharp, and perfectly. Only a few cosmetic problems on the outside but I really don't care. Only thing I've done is replace the plugs, check it all over, replace the pads, brake fluid, oil, ect ect. Only aftermarket piece I've done is exhaust. It has the old 4.6 2v and it has spunk. I could make some ok power out of it, but I decided I'm putting a different engine in it (which is in the works already) so haven't done any mods to it. I need to replace my struts but waiting until I have my new place so I have a garage and can put a coil over setup in it. Which I've also waited purposely on because I'm hoping an IRS deal comes by before I drop on the coil over setup.
I almost had a 97 E36 as my first car, but I'm so glad I didn't do it. M3 parts are stupid expensive and I'd be afraid to mod it and possibly blow it up later.
