Hello.
the cheapest used r9 280x without warranty cost min 190$
I can buy new r9 380x with 3 year warranty for 290$

Im not thinking about eth ROI here, but i would like to mine it aswell
In case mining wont give me profit this year i would like to keep that rig and just wait for better days,

What do you think best option will be?
buy used without producent warranty 280x 190$
or new 3year warranty 380x 290$
for a rig which I will keep and wont sell ?

so the r9 280x are winning i guess, what about the r9 280 ? also DAG is only eth problem ? what about other coins?
used r9 280x is around 200$ in my country
also what producent should I aim for ?

Hello.
After selling my gpu's some time ago Im thinking to come back to minning
Before ive been minning with enermax 1500w and 4x r9 290 (reference, big temperatures, 1400-1500w on the wall)

so i have this PSU left
http://www.enermax.com/home.php?fn=eng/product_a1_1_1&lv0=1&lv1=52&no=191

Im thinking to buy new gpu's,

What do you think which gpu's i should be looking for to fit this PSU ?
Best would be new ones with warranty, with lowest watt/khash
Also should I aim for 4gb ? 8gb ? just in case i would like to keep the rig this time, maybe for some future minning.
Need your opinnions
Thank you in advance
Regards
