Not yet. You can easily mine with i3/i5/i7 or even with older Core2Quad or Core2Duo CPUs for now. Hashrate will not be big, but decent enough, so you can get few coins per day with few machines. Depending on what they will cost, it could be reasonable.
I wonder where these guys are getting their CPU power from? This is on Suprnova:
Rank Donor User Name KH/s XZC/Day

112 Khash/s? Botnets or GPU miner?
It's not KH/s but H/s
OC, with all the respect those numbers cannot be hash/s. Just one of my machines shows 17.95 hash/s locally, but all the machines combined show just about 1.2 something/s at Suprnova (in average). That could be KH/s or something else, but it cannot be hash/sec.
Now we have miner with 204 something/sec!!! That should be about 1000 CPU cores working, when estimated compared with my hashrate and shown number!
Yes, you're right, it's indeed kh/s, i'm a bit confused sorry.
Units are HH (hectohash, 100H) according to my stats, but the pool reported speed still doesn't match the speed reported by the miner.
Very confusing.
