EVGA 770 w/ACX Cooling replacing HIS 7970

post #1 of 4
Thread Starter 
So I got a HIS 7970 iceq x2 a few weeks ago since I did a lot of research and found it to be one of the best 7970 to get for oc/cooling performance. I'm disappointed to say the least with the card, it's not the GHZ version but I got the card stable at 1175/1600 @ 1.2. I honestly think with these clocks the voltage is to high and the card hits 70c fairly quickly.

The question I have is; is it worth returning the 7970 for the EVGA 2/4gb 770 w/ ACX cooling, are those clocks I have on the 7970 better than what the 770 will offer me? Should I fork over the extra money for the 4gb version when I game at 1080p?

if you are going to fork out more than $100 - i'd say it is not worth it for just 1080. i can max out most of my games at 1080 with the 7950 at stock but my cpus are oc'ed.

edit: btw, my 7950 is on air and hit 65C on the core and 80C on the vrms in games. 80C is my absolute max temp i would let my gpu go with the fan at auto.

my 7970 is watered, so i seldom check. last i did it never went over 65 on all temps.

check your case airflow and replace the thermal paste with gelid or something. i only use MX-2.

I'm sure you can run all your games on max settings with your current hardware so why change it just for an extra 5 -8 fps? Not worth it, unless you must overclock the nuts out of your card for benchmarking then go ahead.

OP 1175 mhz at 1.2v is quite good. as long as the core temps are below 75c and VRM temps are below 90c you are safe. try and increase voltage to 1.25v and see if you can push to 1250 mhz. the iceq x2 cooler can easily handle the extra heat. your HD 7970 even at 1175 mhz is on par with a 1250 mhz GTX 770. in fact once a HD 7970 hits 1250+ mhz its just faster than even a golden GTX 770 at 1300 mhz. the GTX 770 is definitely not worth spending extra money.
