This is my build. I have found it works for me. Figured I would share it. I typically do very well with this build.

OK let me first start by explaining my item and spell choices:

Ghost and exhaust - Great for cho'gath, exhaust allows you to hold enemy in place long enough to do significant damage and on top of that with your q will cause the slow effect to last even longer. Ghost could be swapped with TP or flash.

Dorans Ring: I take this mostly for the Mana regeneration effects and health but the added AP is nice early game though I do not build ap cho'gath so dorans shield could work if you have mana runes.

Shureyla's Reverie: I take this before boots as my first item after dorans due to the fact that it is a fairly have mana, health, and health Regen. Helps early survival and ability to stay in lane longer.

Mercury Treads: I take these next for obvious reasons, Magic resist as well as reducing stuns effects. Great for a tank. And in my opinion, only real option.

Frozen Heart: I take this for the mana and armor. Both which are very beneficial to Cho.

Warmogs: Strong HP item and strong health regen item. A pretty much must for Cho'gath. Combine this with fully stacked ult and you will have a ton of health. With armor, MR and health regen you should be VERY hard to kill.

Force of Nature: Strong health regen and magic resist. Magic resist is great if your versing a heavy AP team, if you are not this can be swapped out for maybe rod of ages or another health or armor item.

Thornmail: If game last long enough ill take of thornmail which by this point if played right you should be tanking your team to victory.
