Are Xfx 7850/7870/7950/7970 good? - Page 3

post #21 of 22
Thread Starter 
Thank you guys! I have a 23" monitor 1920 x 1080p ,and i would like to have this build for the next 5 years , now for a lot of gaming but as the time goes,for mild gaming ,just to stay gracefully for some years. (as my 8800gtx do tongue.gif)
I don't know my budget yet,im surely prefer the best bang for the buck as im having financial problems atm,but after summer,after lots of work,this is gonna change.I think i will deserve a new computer buying it with my own money after 6,5 years of keeping the 'old' one.
I may go for club3D 7870 xt Jokercard, or Gigabyte 7870 if price go down more, or even sapphire 7950 Vapor X as its the cheapest 7950 out there, and i think it has way better cooler than xfx as many ppl say.

Honestly John, why are your making requests now when you aren't going to buy your stuff within the next two or three months anyways? Until then, the whole pricing situation might completely change, some cards might be already out of production or have been replaced by others. I'd wait until two or three weeks before you actually going to order your stuff.

Besides that, I own two (owned three) XFX 7970 GHz Edition DD cards. There is quite some discussion going on about these Double D coolers, especially those of the 7900 series. XFX uses a completely different model branded as Double D on their 7800 series.
Word is, for the 7900 series DD, it has serious problems keeping the VRM temperatures down. However the source reviewed that card noted they tested everything in a case with barely any airflow. I neither can agree with the high VRM temps, nor I can deny it. Unfortunatly I can't read the VRM temps on my XFXs like on some other cards. Besides the VRM discussion, I can't complain about the cooler. Using a single card only, the 7970 GHz Edition stays in the low 70 to mid 70°C while the fans are spinning at 45-50% in most games. So under load it is much more silent compared to my old GTX 480 and it keeps the card way cooler. You could keep the GPU even cooler when you manually up the fan speed to ~70%. However starting at 70% the fans are getting too noisy.

Another thing I have to note about the 7900 series is the locked voltage. There is no way you can change GPU or memory voltages on the XFX cards as of now. The problem is, the 7970 GHz Edition puts a whopping 1.213v under load on the GPU. Way too much for the 1000/1050(Boost) MHz the GPU needs to clock. So the GPU creates unneccesary heat there, it should be able to run fine with just 1.6v or at least 1.8v core voltage, resulting in lower temps.


I don't know anything about the 7800 series created by XFX. That design is completely different compared to the 7900 series cooler, it might be better, it might be worse. You have to check out reviews yourself. As for the XFX 7900 series cards in conclusion: You won't get a "bad" card, they aren't very noisy, nor they don't get too hot (can't say about VRM though), they do their job and perform just as well as other brands cards. However there are better choices out there. HiS, MSI or Sapphire seem to offer better designs. But in the end, if you can get a decent price on the XFX or, like in my case, the XFX is virtually the only one available, you can chose this one. My cards are almost a month old now and are doing just fine - besides the bad coil whine.
