My current plan is to replace the R9 290 with a R7 260x that belonged in this computer earlier. Than selling it (The whole computer) And keep the R9 290 GPU and my 750 W Psu. After that i use the money i got from the computer to buy a case,hdd,cpu,mobo,Etc. And above that i will be working in some money so i will probaly have about 1.5-2.5k left so maybe i´ll use that+the money i´ll get for my current GPU (R9 290) and buy like a 970 or MAYBE Maybe a R9 Fury x if the price tag gets lower.
Does that look like a good solution?? I think thats the best way to solve this. I hope you understand my way of thinking even tho my english isn´t that good.
