Bit confused after my upgrade to GTX 280

I have just installed my Zotac Gtx 280 and run 3D Mark 2006 at the standard settings and my scores have not gone up at all from my 8800 GTS 512 mb. To install it I removed physx and the nvidia driver from add/remove programs and then rebooted into safe mode and ran driver cleaner. Then installed the new card and the 181.22 drivers.

8800 GTS:

Overall 13079
SM2 5469
SM3 5655
CPU 3914


GTX 280:

Overall 13361
SM2 5068
SM3 6375
CPU 3890

Did you visually verify that the 181.22 drivers installed in Nvidia Control panel and that you are not running with the windows ones ?
 
Check the usual culprits like anti aliasing, anisotropic filtering and Vsync.

Cards that can maintain a high framerate will give pretty much the same score with vsync on. (although I'm sure you knew it's always worth pointing out)
 
With the same setting in the GPU Benchmark for Crysis:

1680 x 1050
64bit DX10
0 x AA
all other settings Very High
No VSYNC

8800 GTS Avg FPS = 18.18
GTX 280 Avg FPS = 24.18

I have checked AA AF and Vsync in Nvida Control Panel they are all set to Program controlled.

also what mode is the card running at in the nvidia control panel? performance?- quality?

I just spotted that the Multi-display / mixed gp acceleration was set to Multiple Display performance mode. I have changed this to Single Display Perfomance mode. I will run the benchmarks again and see what I get.
 
What's you quad running at?

Your Crysis scores seem about right t.b.h., maybe a tad low but depends on your overclock (card and GPU). That will also have a noticeable effect on your 3DM06 score. Have you run vantage and compared that as it's more geared for the 260/280.

Definately not right...

Why?

Most 280GTX's score an avg fps of 25 to 31 FPS on Crysis benchmark with decent overclocks on Quad CPU's and on the Card as well, based on the above settings.

Hardly miles away so I suspect if the card is clocked a bit and depending on what OC the OP has on his quad, he'd be right in the zone with other 280's.

Personally, I'd ignore 3DM06 scores for a 280 when comparing to a GT.
 
What res is 3dmark running at?

At lower resolutions, I was always under the impression that you won`t see that much difference. As above, 3Dmark 06 is not really geared towards the newer cards AFAIK.

Your cpu is bottlenecking the card at the standard 3dmark06 settings. Clock it to 3.5-4ghz and you will see a massive increase in all 3 scores.

Try running 3dmark06 with 4xAA/16xAF and at 1600*1200+ then you see a difference, well actually you won't the GTX280 score will remain almost exactly the same. ;)

Try Vantage.....

I haven't looked into overclocking yet. But is it largely done by upping the FSB based on the multiplier of 8. So setting the FSB to 375 mhz would get the cpu running at 3 Ghz. Then just look at the idle and load temps.
 
I would just set fsb to 400, leave vcore either at stock or 1.25-1.275V and set ram ratio to 1:1 so you are still running the memory at 400mhz
