XFX R7950 LTC mining-how to setup?

[dennis97519]

Hello, please refer to this topic
Is it effective to solo mine, and approximately how long do you have to wait to find a new block with that card and a i7-3770K CPU OCed to 4.2GHz?
Thank you.

I have 16 GB of system memory and 3GB  of GDDR5 memory.

Like can anybody tell me the optimum command line to use to start CGminer with AMD Radeon 7950 card? If I solo mine how long would it take to find one block?

This is the answer
but approximately how long it takes to find a block for a speed of 600Kh/s?
