Can't decide between Gigabyte 7950 or 7970

post #1 of 15
Thread Starter 
Hello,

I'm struggling to decide between these two video cards for a new build. Is the extra £60 worth it?

http://www.dabs.com/products/gigabyte-ati-radeon-7950-hd-800mhz-3gb-pci-e-hdmi-windforce-3x-oc-7XN5.html?refs=43280000&src=3

http://www.amazon.co.uk/gp/product/B0074VVTPI/ref=olp_product_details?ie=UTF8&me=&seller=

Please could recommend any alternatives? (I chose Gigabyte for the 3yr warranty and return possibly being easier if anything happens).

Get the 7950 and overclock it. I don't think it's worth the extra money.

Thank you for the quick reply. I was swaying towards the 7970 at first but reading up here it seems the 7950 is preferred (from my limited understanding) and the saving would be handy. I have not overclocked so I would need to read up although is it straight forward?

overclocking is easy, make sure you get a 7950 that is not voltage locked. use msi afterburner to overclock.
I believe the gigabyte windforce series, as well as some msi cards are not voltage locked.

Gigabytes's 7970s are voltage locked. Not sure about their 7950s.


OP just keep in mind that your 79xx cards are not guaranteed to overclock well. I've had two 7970 in the past and they wouldnt do more than 1060/1100 core.

My 7950 Gigabyte WF3 has ASIC of 57.7 and it hits 1250/1800 on 1.3V. This is better than an OC version 7970.

After refunding 2 sapphires for artifacting issues at stock yes I hit the jackpot ^^. I dont run it at those clocks though as there is no need with BF3. My cpu is at 4.6Ghz and I run my card at 1150/1550 on 1.20V and get a solid 60 fps the majority of play time. Obviously not solid 60 in a full 64 man but a couple of frames is hardly noticeable.

Go for the Gigabyte HD 7950 OC. you can manually overclock with voltage tweaking. there is a boost BIOS (F3 version) released by Gigabyte with 1 Ghz boost clocks. you could try that if you don't want to manually tweak. But for optimum voltage manual tweaking is the best.
