^^ Cooler Master PSU , AFAIK from TDF and other experienced sources, are not to be recommended with a new GPU if the buyer already has plan to buy a new one. Anything above 500W is good enough, GeForce GTX 760 - 30A and a 500W PSU minimum, below are nicer stuff...

let others come back with more comments...
^^ I meant at least 500Watts, it is the standard recommended supply for GTX 760 all over. there is nothing wrong with CX series. CORSAIR Builder Series CX600 600W ATX12V v2.3 80 PLUS BRONZE is a very good PSU indeed. Seasonic, yes obviously best at the price point though.
Go for GTX 760. Performs equally to GTX660ti, but is a newer gen hardware.
can my psu can work for only one month at least ?

now i want 760 even quicker760 will eat a gtx 580 oc for breakfast. A 7870 is a bit faster than a 580 too.
