To have overclocking ability would probably add a minimum of $200 to the project, maybe more.
No, there's not that much difference between an i5 and an i7, I have both and don't really notice a difference.
So whatever I have thought and finalized is OK.
What's the difference between different memory config. ( single, dual, quad channel) in one stick of ram?
Single utilizes the ram each in different channels. Dual uses unique a channel for every two ram slots. Quad uses a unique channel for every four ram slots. This is the reason why you have to put in ram in specific slots if not all of them are occupied. The slots are arranged differently for different MB manufacturers. But most times, if it is dual channel, slot 1 and slot 3 are supposed to be occupied if using only two sticks. Most consumers need only dual channel. Quad channel is meant for servers and workstations where ram is heavily used.
Your PC will run fine in single or dual channel. Dual channel means utilizing the correct 2 or 4 slots. If you use just one slot, it will be single channel. Dual channel is faster, but you'd be hard pressed to notice the difference in most operations.
The RAM stick itself is not "single" or "dual" or "quad". It's the platform (motherboard) that determines that. With one stick, you are going to be in single channel, regardless. The difference between one 8 gb stick in single channel and two 4 gb sticks in dual channel is small.
