What I want is: buy a cheap psu until I get better one then I might use two psus at once but if not I'll get at least 1600Watts
but there is no option for Me such as entire system takedown because I will have 6 7950s
Not sure this is possible, you can only attach one PSU to the motherboard and why do you need 1600Watts?
6 OCed 7950s take 1500Watts??? Or am I wrong?
Crossfire and SLI only support 4 cards. So the 6 cards is not possible. And you need X79 platform to support 4 cards, unless you run 2x 7990's. This adds to cost, also running 4 cards does not necessarily increase performance, scaling becomes horrible past 2 cards and you will experience negative scaling in many cases. On top of this crossfire and SLI drivers running 3+ cards becomes a headache.
Also if you run really high resolutions like 4k monitors then the HD 7950 would not be too great because the Memory bus is 380 bit and commands 3GB(Vram does not stack so you will still only have 3GB)
So in theory 2 R9 290x would perform better due to better Vram handling with 500bit bus e.g.
To be honest, if you were seriously considering to purchase 6 GPU's then you are far from read enough on computers.
