P7H55-M is a good choice, My friend has the same motherboard with the same I5 and trust me, He is not disappointed.
EDIT : Sorry, He has a I5 750, Not 760.
As for the RAM, 2x2GB of kingston should do the job. Don't overclock though, Reduces greatly the lifetime of your memory.
Personally, I never had any other RAM brands than Kingston (And I believe I had Samsung RAM once, But it was bull-.)
I didn't really follow up the whole conversation, But if you are building this computer for yourself, 4GB is the strict minimum for a great build. 6GB is even better, But I wouldn't go any higher than 6GB. Waste of money in my opinion, But some people find use for it.
