Im not that big expert but what i see you have probably just some kind of stock PC, not mining rig, just single random gpu (whats the model?)
If you think CPU is your ram memory that I think better leave mining before you start yet and get in trouble with more advanced mining jargon,miners,pools, ports and settings etc.
And to be honest if look at this economically you will be in loss with your electric bill by mining maybe! 1 ADZ a day from all shares in pool
This is now for asic miners job and just wait month and you will see first Antminers D3 in action with 15GH/s each
If you stubborn you can let it try if you know how to setup your comp for mining but this is like compare calculation power of processor Z80A @ 3.528Mhz from ZX Spectrum (8bit-1982) to i7-7700K @ 4.2GHz (64bit- 2017)  you know what I mean
To save your frustration I not recommend you to think about mining x11 algo with this PC..
