Fatecoin was removed because it does not sync. Memorycoin was pulled because it implements the Kimoto Gravity Well which is vulnerable to the Time Warp Attack. Muniti was pulled due to the huge premine.
The GPU Advantage for Maurucoin is currently greater than 10, which is the limit to be listed. If optimized CPU miners are released, the GPU Advantage will drop and coin can most likely be put on the front page again.
I have added GiveCoin, HighFiveCoin, Limecoin, VirtualCoin and Logicoin to the front page. I will be creating individual info pages for each shortly.
Groestlcoin has been added to the list. After a tip from srcxx, I checked the hash values reported on the configuration spreadsheet. I found that GPUs only have a 4.9 advantage over CPUs. Check the Groestlcoin page to see the calculations.
The results are in: The GPU Advantage of Primecoin is 51. That means a current GPU (Radeon R9 280x) has a hash rate that is 51 times the hash rate of a current CPU (AMD FX-8320).
Also, I am done with the major design changes. I will be updating coin information now.
There are now two GPU miners released for Primecoin:
1. PrimeGPU has a GPU miner for AMD 7950/280x and up. The cost is 65XPM per GPU. Info on Bitcointalk and Peercointalk.
2. Claymore has released a gpu miner with a 10% developer fee. It is available for download on Mega. Claymore is on the ypool chatbox.
A third developer is looking for a 50BTC bounty for his nVidia miner. His thread is on Peercointalk.
