5)Need suggestion from u guys^^help me with my build(FOR GAMING AND SURFING)
Playing today's games you are better off with a dual core like the E8500, although some games make use of quad core now.
More games will use quad cores in the future. You could save some money and get a dual core for now, change if you need to later.
You can also change you RAM. You do not need 1066. You will be fine with 800Mhz (PC6400). And you should get 4 gigs.
I'm not going to try to explain CPU cache... even if I happened to get it right you likely wouldn't understand it. It helps to move data through the CPU, sure more is better. For your needs a GOOD graphics card is far more important.
Less on the RAM, less on the CPU, more on the monitor will get you a better gaming experience.
Your processor process all the mathematical data through your computer (the exception being graphical and if you have a sound card; audio). It can only hold so much information within itself at once. This is its cache. The rest it stores in your RAM for safe keeping, and then if that fills up it stores it in the paging files of your hardrive. As information passes through your processor it moves from the paging files, to the memory, to the cpu cache, because the cpu cache is the fastest type of memory in your computer. Memory comes in second, and paging file third. The more "powefull" the processor is, more often times then not the larger cache it has. Larger caches and more cores allow your computer to handle more information at once, great for complex programs and multitasking. Get it?
