ok...so ive decided to wait since theres apparently a problem with my psu power.its a cheap 400 w techcom psu...i understand that i need to get a more powerful and quality psu first..these are the questions:
1) will a 500w psu suffice for any of the cards mentioned(460,470,550,6XXX)?
2)suggest a 500 w psu for a max of 2k
3) im going for nvidia cause ive heard that amd gpus perform terribly with physx enabled..is this true?
4) gtx 470>460>550?
