I have HD, Monitor, Keyboard, Mouse, Speaker, Headphone, DVD burner ready.
1. Do I really need a 850w power supply to be safe for future upgrades? Or 750w is more than enough.
2.Which video card (two from above) is faster?
3. Is the on board sound card good enough?
4. What cooling add-ons do I need to get?
Thanks for reading, I am very open to suggestions, please help me out and point out anything I need to watch out for this build.
