Hello guys...i have a question for u that make me nervous,and that is: a month ago my OS was Win7 Proffessional N on 32 bits,which not recognize all my memory ram,i have installed 4 gb of ram,and usable i got 2,33,and one friend told me that my processor is moving a little slower,so i format my pc,and i installed Win7 Ultimate on 64 bits.From that point my pc recognize all my memory ram and the processor,i have a dual-core Intel B960 at 2,2ghz...but...ooooohh...i don't see not even one difference since a have a 64 bits,so it is moving the same like i have 32 bits,in games is the same performance! Let me explain u a little bit,i buy Assassin's Creed 4,u know is the last game from the francize,which is the awseom game i ever play,so..when i have Win 7 Pro N 32 bits,this game is moving a little bit laggy and have FPS drops,and when i install Win7 Ultimate 64 bits,i do not see not a single damn difference,is moving the same althought now i have all the memory ram,and in 32 bits it see only 2,33 gb from 4 gb?? So my question is,why is not even one difference in my laptop's performance,since i make the change from 32 bits to 64 bits! Let me tell u my specs: intel B960 processor at 2,2 ghz(is a little old,but is not that stupid,i think),4 gb ddr3 ram,500 gb HDD,and my video card is NVidia geForce 710M with 2gb dedicated VRAM(the driver for it is 307,17).So ...if u can help me,please do it!
