Hi everyone. I started buying my computer parts and **have** eveything I need,but the following: **CPU ***GPU ******OS *********Aftermarket heatsink. I was going to wait till I could purchase all the above before placing my next order,but the graphics card was the main thing burdening my wallet. However I was like: "duh" the CPU has built in HD 4000 graphics I could just go ahead and hold off on the Graphics Card and atleast be able to fire up my system and check everything is in good working order,as well as have a PC that is working rather than a cardboard box full of plastic/metal. My questions are: 1: If I were to use the Integrated graphics for the time being...after I bought a GPU in the future the CPU would automatically detect a aftermarket Graphics card and **completely stop** using the built in one right ?. 2: Since I am not going to be using the Integrated graphics for long term...I should go with a cheaper CPU with less built in graphic power ? (refer to Q:#1) cause after I buy the GPU I won't have no need for it?. 3: Any one have any CPU Heat sink suggestions that will fit my case (HAF 912) and as far as OS goes do I **really** need a fancy version of Windows 7 or just the most plain ? I only plan on playing games,music,and minor web browsing... Thank you all sorry for my large thread.
