7970 or Asus 7950 Direct CU top (V2)

post #1 of 9
Thread Starter 
Hey everyone, I just bought a 7950 Direct CU top which is faulty, it only shows a few dots during POST but when windows starts, it works fine. Needless to say, it is going back for an exchange. However.......

It was £260 from amazon and I can get a 7970 non GHZ for around £320 is it worth the extra £60? I was disappointed to see that on a maxed out Hitman Absolution benchmark, it only achieved 27 FPS and when overclocked, 32 FPS

It clocks to about 1100 Core and 1500 Memory.

Is it better to have an overclockable 7950 with the (amazing it turns out) Direct CU cooler or to get a 7970 with a lesser cooler and potentially less OC headroom?

Thanks for any input, I don't have long to decide!

I guess if money was no issue (it is but for discussions sake) how much more would I get from the 7970 at it's best OC over my current 7950 OC?


Cheers, James

Definitely keep the 7950, you won't get 260 for it even with mild use.

You will possibly see a 10-15% boost, not really worth the extra premium when an 1100/1500 7950 will smash a stock 7970.

Hey, sorry, I'm not selling the 7950, it is going back under warranty so I have the chance to upgrade, the £260 value is still firm as I only bought it yesterday so is the total investment so far. So the question is, is the 7970 worth the extra £60? It will be overclocked also though thumb.gif

Not quite. It takes a bit more overclocking to match a 7970. From what I saw in the "Post your Heaven 4.0 screenshots" thread, my card matches 7970s, and its just short of 1300mhz core.

Id say go with the 7970 if you can swing the extra bit of cash. $70 isnt that much when you consider youll probably have this card for 1-2 years. With a 7950, at most your going to clock it to ~7970 levels. With a 7970, youd be able to exceed that. Youd easily go over 7970 Ghz Ed. levels. If the 7970 you are thinking about buying is a reference model with a reference blower cooler, dont do it. The cooling on those ref models is horrible.

1100/1500 is pretty bad for a 7950 to be honest.

Just to update so far I am running 1200MHz core and 1550Mhz Memory at 1.25V
Absolute max temp 70*C

This is Unigine Valley and 3DMark 11 Stable
What game benchmarks would test it's true stability?

what clocks were the HD 7970s running at ? most benchmarks and games show a HD 7950 needing 50 - 75 mhz to match HD 7970. so HD 7970 Ghz(1050 mhz) is matched by HD 7950(1100 - 1125 Mhz). also the average overclocks for HD 7950 is 1100 - 1150 mhz.

Ah I see, so what would be the average overclock of a non GHz Edition 7970? I wouldn't get a stock cooler one either, too noisy!

Probably a bit less than what you have now. Might be able to match the clocks, not entirely sure. You might see a tiny bit of a difference in performance, but I'd honestly just keep the 7950 if it's working fine.

Thanks for the replies everyone, I am sticking with the 7950 as I had a chance to play with crossfire, my CPU was bottlenecking terribly so i'll same some £ towards maybe a FX 8350.
I have however started a new thread if anyone can help as it seems that my replacement is also not working with my setup. It's here if anyone can help smile.gif
