HIS or XFX or GIGABYTE 6770

They are all great really, no brand of those has problems. But sapphire has been the best partner for AMD along the time and i have been using it since the Radeon X1900
so i recommend the flex

In your case, I would go with Gigabyte. They are a trusted company with the experience I had with them. I am not to sure about Sapphire and HIS, though I've owned their cards. Never had an issue with them. If you live outside the US XFX is definitely NOT a good choice as their service and support outside the US sucks.

In you are in the US - XFX.

I have bought numerous HIS cards over the years, and they all worked well, with excellent coolers. I own one XFX that is also still kicking, and I've installed some Sapphires for others that have never failed. I've not bought a Gigabyte GPU, but they are not one of my favorite mobo manufacturers.
Incidentally, the Extreme Power line from Crappermaster is one of their worst; inefficient and most are overrated. HardwareSecrets has reviewed most of them. A quality modern PSU has full range active PFC (no little voltage switch) and some level of 80+ certification for efficiency. Seasonic, Antec, Corsair, XFX, and Enermax/LEPA are among the better brands. A 380W Earthwatts or 400W Builder would have no trouble with a HD6770.

HIS IceQ X HD6770 looks good and seems to have good cooling.

tanx for yur reply frendz   ,So i wud go fr HIS or Sapphire or GIGABYTE ,,As yu told XFX wnt b gud if v r outside US...Again there's Confusion btwn those 3 brands As i seen the spec of brands providing 6770...

Sorry for My BAd English  

Thanks,

yes mate that mobo will support your card.

where dya live btw ??

The flex has a good cooling, and the HIS has the highest clock.
but i would go for the flex, i can OC it to 880 easily.

India

but HIS 6770 already got 880Mhz without OC,,?bro do they have any difference in performance regarding this core clock or memory clock speed,Actually Im new to tis sector so..

Thnx lutfij,,,i ll go for HIS Iceq....  

My Mainboard support PCI EXPRESS 2.0*16 only,, but HIS 6770 is PCI express 2.1*16,,,ll my Mother board support HIS??Can i use PCI express 2.1*16 HIS GPU In my PCI Express 2.0*16 mother board...?  

Yes you can.

PCI-E 2.1 cards are backwards compatible to run 2.0 cards and the 1.0 cards as well. its actually the same - no big difference from 2.0 to 2.1.

i saw your mobo in the first post. relax - pick it up already and select "best-answer" so we can close this thread  

I will choose gigabyte for his big fans and good quality~

Get HIS 6770 or Sapphire6770 Flex.As I know that Sapphire has a good cooling system in thier GPU's and Sapphire has been a best partner of AMD for a long time.so I recommend Sapphire 6770 Flex.

Best answer selected by srii.

Thank YOU for the vote mate! Happy gaming with that IceQ!
