So purchased one of these from OCUK the other day. Lovely card, nice and quiet thusfar... went from a 6950 (around 4.5k on 3dmark) to this (6.3k on 3d mark).

Does this increase seem reasonable or a little low?

Furthermore, should I consider overclocking the GPU a little? Is there plenty of room for overclocking or is it best to keep it at stock? (this thing runs at 900/5000 I believe?).

Thanks folks.
 
Well it's going to run nice at 900 core.
I had my first 7950 running at 950 core and it was comfortable with BF3 @1080p.
I'm running my new 7950 between 1000 and 1050 core just because it can very easily.

If it runs your games OK then why bother, but I'm guessing that card would give a nice boost with little effort.
 
Get it up to 1000Mhz. just because it can soooo easily, it's a nice round number :)

You keep that 7950 @ 950Mhz and you have me outperforming you on my 7870 @ 1200Mhz, you have no choice now :p

Could you give me some of your benchmark results? Thanks.
I can't help perhaps my 7950 is under performing?

I have a q6600 running at 3.2Ghz also.
 
I only use Heaven to test and compare my overclocks but if you post the settings that you use in 3d mark and which version I will find a copy and try it later.
 
Sure, tbh I just press the "run" button without changing anything (I think 3dmark11 just has default settings or something?)

Could you let me know your Heaven bench settings? Ive never used Heaven before...
 
Ya of course, I will post the Heaven settings later after work.

When I used 3d mark I had the advanced version so the settings could be changed but if it is the free version I could use that.

Hmm perhaps the better CPU in your case + the massive 300 MHz overclock could be the main reason?

It's 225Mhz on the core and 175Mhz on the Memory, yes that certainly makes a difference. With my clocks as they are its about ~20% faster than a stock reference 7950.

Did you save the link to your 3DMark 11 bench? i'm assuming its a 3DMark 11 bench, i need to see the full scores to give you a better idea of whats going on.

[Edit] hang on. i have Avg on my computer, let me just bench it.

Blimey reading more into this a 7850 at 1000MHz is approximately 20% faster than at the stock 860MHz.

Does this sound right?

If so then your 1200Mhz overclock represents a MASSIVE increase in performance surely? Added to that the better GPU?

Erm?

On exactly the same settings they used i got quite a lot more than the 7950 they had there, quite a lot more than the GTX 680 aswell.

65.7 FPS

Now it should also be said that they are using 12.1 drivers, i'm using 12.8
But yes, it looks absolutely right that i'm outperforming you if your only running 900Mhz, which your were right to say 300Mhz, sorry.

Have you tried running it at 1100Mhz / 1400Mhz ?

Not tried any OCing yet tbh...but may tonight...tbh... even without OCing the performance is fantastic in games...

I think the point I was trying to make in that previous post was that at 850MHz the7850 was 40fps in AVP and at 1000Mhz it was 50fps so that represents a 25% increase actually just by OCing by 150MHz. So going from 850Mhz to 1200MHz (350Mhz Overclock) will most certainly yield something special...possibly in the region of 40-50% increase in performance? add to that the better CPU, so I think a 3dmark score of 7k vs my 6.3 probably sounds in the right region....
 
Oh and at reference clocks (I downclocked the factory OC from 880 to 800), I get 7k.

But there is a gap between Q6600 and i5 2500k =]

@ 1200Mhz / 1500Mhz, yes somewhere between 40 and 50% is about right. enjoy it :D

If you need help getting there let me know :)
 
I reset mine to stock (880 core 1250 mem)

Score 7357


@ 1100 core 1500 mem

Score 8527
