[rjpullie]

Hi, please can anyone help, my mate has built a system as below and hes only getting around 7500 3dmark05
p4 3.0ghz 2MB 64BIT
2gb corsair xms2 400 (4 x 512)
2x xfx 7800gtx xxx gamer editions
ABIT NI8-SLI
600w silverstone atx2 psu..
etc.. etc..

thought it may have been cpu bottleneckk so i managed to get cpu overclock of 3500 mhz and score got to almost 8k.

any help greatly appreciated

Sounds like youve only got one card activated

yeah i thought so so checked i enabled it in bios switched flip card to sli then when booted into windows enabled when the sli message appeared,
i too have sli system with 2x 7800gts and a fx55 and it eats that for breakfast..

Have you checked to make sure v-sync is turned off?

Is your mate is choosing the 3d mark 05 profile setting in the 7800gtx control panel when testing...

Afraid your score looks about right.
I used to have a PD 3ghz & with 2x7800gtx got 7700 in 3dmk05.
Thats why I went AMD & got 13400 instead.
Reckon you would get 4400 in 3dmk06 which is not bad though probably due to dual core.

Are PD's realy THAT slow!!!

I have an opty 144 (@2.7Ghz) with a single GT that breaks 8000, thats truelly awful if its correct

That is bad, single x1800 XT here on an A64 3500+, all stock gets about 8.5k, surely he should get more than that with 2x GTX's.
