Graphic card

I have read your review of HD 5770 graphic card, which was very good and I have decided to buy one of this card. please suggest me which manufacture card I should buy.
I have PSU of 450 watt and mb of gigabyte GA-MA 78 GM s2h. So tell me also whether my PSU and Mother board will handle this card well.
Please reply quickly.

    Unless it is quite poor a 450w PSU should handle an HD5770. As for which card to buy the main differences between the cards will be the cooler, warranty and price. The HD5770 is pretty cool and even the reference fan does the job fine so the cooler doesn't matter that much. I would decide mainly based on price.
    Also there are versions of the HD5770 with 512mb of memory. They should be avoided unless you can't afford a 1gb version of the card.

    I have got the Zebronics cabinet Dew. this cabinet has one side 80 mm fan and one back 80 mm fan.
    Present I am having HD 3450 graphic card in crossfire. I am facing no heat problem.

    Do I continue with the same cabinet or purchase a new one, when I install new MSI 5570 twin frozer with new 500 watt PSU.

    I have selected this one: http://zebronics.net/Zeb_Bijli.asp

    Please advice.
  4. Do you mean the MSI Hawk HD5770? The HD5570 is a different and much weaker card. I don't think either of them have a "Twin Frozr" although the cooler on the Hawk card does look very similar.
    Anyway, that case should be fine. The HD5770 is actually very power efficient and low heat. Are you really using crossfired HD3450s? If so you are in for quite an upgrade as those aren't gaming cards at all.

    Yes I meant MSI hawk HD 5770 with twin frozer. so tell me whether this cabinet which i am presently using will be ok for this card.
  6. Yeah, like I said it should be fine.
    The Hawk is a good card. Nice fan and it allows for overvolting for a high OC.
    What kind of processor do you have in there and how much ram?

    I have amd Phenom 550 3.1 ghz black edition and 2 gb ddr2 ram.
  8. The processor is good, 2 gigs of ram is ok but 4 would be optimal.

  11. The GA-MA785GM-US2H does have ACC which allows you to unlock the extra cores. It is not guaranteed to work but the odds are good, somewhere around 75%.
  12. what are the dangers in unlocking process. any chance of harming cpu .
  13. Nah, if they are no good then most likely the system will be unstable with them unlocked. If so then you just go back into the BIOS and lock them again
    It's possible it wont be able to boot if the cores are defective. In that case I'm pretty sure the motherboard itself will relock them after a few failed boot attempts. If not then at worst you will need to reset the BIOS settings which involves taking a jumper off your motherboard then putting it back on.

    pcie 2.1 is slightly faster than 2.0 BUT pcie cards are backwards compatible which means your 5770 will work on any pcie slot, doesnt matter if its 2.1, 2.0, 1.1 or even 1.0
