I cant tell the difference between them other than the obvious £20 price lol. Also if there is another better mobo around the same price can you tell me please?

    Sorry to ask this but im completely useless with computer parts lol, what is the better of the 2? or what would you buy to be more futureproof and reliable?
  3. Unless you need an eSATA port or ports i.e. external HDD <and/or> a Monitor that requires a DisplayPort and is 2560x1600 resolution AND you don't have a Discrete GPU then buy whichever MOBO is cheaper.

    Neither is more 'future proof' than the other.

    Ok buy if i buy the cheaper mobo the usb 3.0 ports will still work on my external 3.0 HDD right? im sorry i dont understand what most of this means lol. i have GTX 670 gpu and id only use the onboard mobo gpu if that 1 broke and i had to get a replacement. my monitors 1920x1080 but im buying a benQ 24inch 120hz 3d tv if that makes a difference?
  5. External USB 3.0 drives will still work but are only bootable if the USB 3.0 ports are Intel USB 3.0 ports and not third-party; see the MOBO's manual. USB 3.0 for external dives is fine 'IF' the data is large, small files are very slow. In contrast, ASUS Z77's offers USB 3.0 UASP Mode & Turbo Mode which corrects this problem. Most external drives current don't support UASP Mode.

    For most folks I recommend eSATA over any form of USB for external drives.

    In addition, Thunderbolt is the newest and improved way to connect devices (displays, devices, etc).

    sorry but there is more too it than that. if you plan to add a second graphics card, the d3h only has 1 3.0 x16 slot and then 2 2.0 x16 slot at x8 and x4 where the ud3h has 2 3.0 x16 slots running at x16 and x8 and then 1 2.0 x16 running at x4.

    you also gain these connectors and features over it

    1 x power button
    1 x reset button
    1 x Clear CMOS button
    1 x Voltage Measurement Points
    1 x BIOS Switch

    Onboard OC Features
    Lucid Universal MVP Support
    Switchable Graphics
    GIGABYTE EZ Smart Response
    1 x DisplayPort
    2 x eSATA 6Gb/s

  7. Where do you get your information from. I think you best check the website. Apart from a few xtra buttons like clear cmos and standby etc they are exactly the same. Where you got your pcie3 info from ill never know lol
  8. Oh i forget the dp out too lol

  10. Better boards in the UK I guess... :-)

  11. And your link don't work lol
  12. Compare here. The express 3 slots are all the same and atx power is 8 pin. Like I said, a few buttons and a dp that's it.

    http://www.gigabyte.com/products/comparison/list.aspx?m=1&ck=2&pids=4325,4441
  13. And a different array of headers and ios that's it. All pretty much the same in the UK. not really worth the upgrade of £25 here.
