Yea, that's quite a nice highly optimized GPU miner you have there. This is like when Maxcoin launched with a couple guys having Nvidia miners on day 1 mining 5000x faster than everyone else.
XCN price is a train wreck waiting to happen until there's a long and reasonable explanation about that address.
All you really have to do is look at precedent we already have for coins where any hidden GPU miners are involved. Every single one of those coins had apocalyptic price crashes from the initial price. The coin is a complete gamble at the moment. This concludes the XCN r0ach report.
Having GPU miner as part of the release bundle at very launch has to be mandatory for coin to be considered as "fairly" launched. CPU2GPU ratio is irrelevant. Even if it is 1:1 it simply has to be released immediately.
