7750 2GB or 7770 1GB

Hi Guys I was looking into buying a low end gaming pc and have complied a list of compoments..but I have found 2 GPUs with about 20 pounds difference between them.

SO...

XFX Radeon HD 7750 AMD Graphics Card - 2GB (£72) or ARIANET Radeon HD 7770 1GB (£89)

so which one would produce the best graphics?

oh and heres my future rig...If it counts:

Intel Core i5 3470T,
Gigabyte GA-Z77X-D3H, Intel Z77
8GB (2x4GB) Corsair DDR3 Vengeance Jet Black
Seagate 2TB SATA III 7200rpm
600W Cooler Master GX Lite
Microsoft Windows 8 64bit

Thanks in advance :D

More about 7750 7770
  1. 1: dont get a t chip. they are not worth the energy savings
    2: get a h77 motherboard like the asrock h77m
    3:there is ram at scan that sells for 30 pounds. low profile as well
    4: get a better power supply like the xfx 550w.

    you dont need 2tb unless you got a couple hundred movies


    and for the video card, id suggest the 6870 if it isnt too much more than the 7770. if you cant find a cheap 6870, get the 7770 1gb. way better than a 2gb 7750
  2. ok thanks for the quick reply

    Is a this better

    Intel i5 3450
    ASUS P8H77-V LE S1155 Intel H77 DDR3 SATA 3 USB 3.0 ATX
    XFX HD 6870 AMD Radeon Graphics Card - 1GB

    And I am getting most of this stuff from scan and the cheapest 8gb ram is for £40
  3. i dont even think the 7750 will push far enugh to use the vram of 2GB

    No. Get either a Z77/Z75 board if you want to overclock, or a B75 motherboard if you don't. They're usually cheaper than H77 boards.

    As for the graphics cards, a 7770 1 GB is better than a 7750 2 GB; the extra memory won't make much difference because if you're running stuff that requires more than 1 GB then most likely both cards would be running too slowly anyway.
  5. Edit: Double post.
  6. I'd change the i5 into an i3 3220 and put more money towards the graphics card.
  7. Yah, a 7750 with 2GB is kinda silly in my opinion. The 6870 is a decent choice.

    clearly you have not seen that he is using a i5 3450 which WONT overclock either way

    Clearly you have no idea what you're talking about - the Core i5-3450 can be multiplier overclocked.

    if its not a k chip, its not going to overclock more than 4 speed bins. i dont even know where you got the idea of overclocking non-k chips but ok.

    and if he was to overclock, he would be getting a k chip?

    Hi aatif - agree with Troll on t chip & PSU, agree with Sakkura on MOBO, and agree with all on NO 7750 card.

    Overclocking by up to 4 speed bins is still overclocking. This overclocking is only available with a Z77 or Z75 motherboard.

    im sure breaking all your warranties from intel is worth a max of 3% gain in performance? and that it could easily fry your chop given intel bins their non-overclocking chips for NON-overclocking purposes

    While performance doesn't quite scale proportionally with clock frequency, you can expect more than a 3% performance improvement from increasing the clock frequency by more than 10%. Also note that a 400 MHz clock frequency difference is bigger than the difference from the i5-3450 through the 3470 and 3550 to the 3570.
  15. uh huh. if i run my i7 3770k at stock speed and run it at 4.3ghz, there is like a 2 sec difference between each other when i rendered my movie. so you are saying that 2 sec of difference is worth breaking your warranty. im sure it is

    not to mention z77 boards do cost more than h77 boards or b75. i dont see your point at all
  16. The price difference between a cheap Z75 or Z77 board and a H77 or B75 motherboard isn't any bigger than the price difference between a Core i5-3450 and a Core i5-3570.
  17. Hi everyone, sorry about the late reply

    Thanks for the replies it has helped me a lot in picking the components

    Just to clarify before I order the items is this what you recommend:


    Intel Core i5 3450 (I dont plan on doing any overclocking)
    ASRock H77M Intel H77 Micro ATX[H77M] / Gigabyte GA-B75-D3V Intel B75
    XFX HD 6870 DD Cooled XXX AMD Radeon Graphics Card - 1GB
    Corsair Memory Vengeance Low Profile Blue 8GB DDR3 (Dont know how I didnt see this...Thanks :D)
    Seagate 2TB SATA III 7200rpm (I have a lot of old videos and games...)
    XFX Pro Series Core Edition P1-550S-UKB9 550W Power Supply
    Microsoft Windows 8 64bit

    The total cost will be £567 (Inc VAT)...Plus extra for Case

    Buying all items from scan.co.uk
  18. That looks pretty good.
  19. H77 boards tend to have superior audio quality to B75 in my experience. You might want to consider that.

    Just look at what audio codec is included. In this case the Gigabyte GA-B75-D3V board has Realtek ALC887, which is good enough as long as you're not a hardcore audiophile (output signal to noise ratio 97 dB).

    The ASRock H77M has a Realtek ALC892 codec which offers exactly the same audio quality. It does offer a little more flexibility if you're going for a surround speaker setup though.
  21. Im just planning on using a basic headset so surround sound isnt really a problem
