Want to get a 3550 + 6850 system

Hi guys, this is my first time to homebuild machine. I'm not sure if the system is okay.

Intel i5-3550 $210
Sapphire 6850 $150
Gigabyte GA-Z68A-D3H-B3 $110
G.Skill Ripjaws 2X4GB DDR3-1600 $46
Samsung 1TB 7200RPM 32MB SATA 3.0Gb/s $90
Rosewill Hive HIVE-750 750W $90
Rosewill R5 Black Gaming ATX Mid Tower Case $70 ($30 off with HIVE power supply)

Some other questions:
1) Is 750W PSU too much? Is 650W enough?
2) Is head sink necessary for 3550? Do I need to get one?
3) I'm not quick familiar with the motherboard. Is gigabyte better or asus?
4) The hard drive is damn expensive. Do I need SATA6.0Gb/s for a 7200RPM hard drive?

Thanks a lot guys!

  2. Budget? Usage?
  3. As I listed in the original post, the sum of the prices should be around or less than $800. If I want a 3550 and a 6850, I guess I would use it for gaming but obviously I'm not a game enthusiastic. Don't you think so?

  4. You will not be overclocking anyway so use a mb with an H77 chipset . That will have guaranteed compatibility with the 3550 , where as a Z68 might need a BIOS update .

    Your build needs a 450 watt psu . 80+ bronze or better .


    If its for gaming I'd spend more on the graphics card , and less on the case and psu . Again if its just gaming you can trim the RAM to 2 x2 gig and not affect performance .

    Potentially you can save enough on case/psu/RAM to include a much more graphically powerful Radeon 7850 . Whether this makes sense depends on other uses for your pc and the resolution of the monitor/screen you will be using
