davidarad02 :
can you just link me a store and a budget in your currency where I can check and tell you what I think is best for you?
Amazon.com or newegg (Amazon preferable), budget up to 330 USD (Weight matters, each pound adds $10 to the price of GPU), (I have MSI 100ME Gtx 970 in my mind), Should come with a backplate preferably, Should be at least 4gb GDDR5, no used ones or refurbished since i cant return the card and the guarantee doesn't work where i'm from, cant change power supply (will be using CX600 for now), max resolution 1080p, processor i5 4690k stock clock liquid cooled with CM Seidon 120V. and the G1 gaming cards fit, just found some pictures on pcpartspicker, it fits just fine.
Thank you for the help!
EDIT: Don't count the weight money on the GPU's price, i can afford up to 400USD (GPU + Taxes and its shipping weight) all together
