Ive heard this argument so many times ok so, in Australia it is hard to find reference r9 290s. When they are in stock they are $450 dollars. 2 of them 900. Already more expensive than the 980. Then two water blocks plus fittings plus back plate $320. About $1200 for those. It is about $950 for a 980, waterblock, backplate, and fittings. They are always in stock, they require less power, and I just want one.
And remember, "about" is in bold
