It is a good build but no need for all that ram for gaming 12GB max. Better build for gaming would be I5 2500K with a P67 motherboard and 8 GB ram with either of the cards you mention. Single card setup would run fine on a 600watt PSU!
whats the diff bet X58 1366 and 1156 sockets regarding gaming I havent found any major difference the only reason I opted for 1366 is it supports hexa cores hence I wont have to go for a total mobo+processor upgrade a processor upgrade might suffice
So what resolution monitors should I take could you suggest some, I am buying 20" Dell coz GTX 570 gives nearly 45-60 fps on this resolution ,at 1900's its a little better than 6970 and higher it goes down the hill while 6970 maintains itself
Could you suggest a better GPU for this resolution monitors which might stay a year before I upgrade my GPU
