You can't possible use that much RAM. More than 16, and probably more than 8, will just sit idle. Also, going 2500K would save you a bunch of money. If you're not going for the best possible gaming build ($2500?), the CPU's maximum OC won't matter and the 2500K will perform on par with the 2600K.
Yeah, check out the Tom's list. I recommend 120/128gb or larger.
