3dmark06 scores

I have an ASUS SLI deluxe mother board and an AMD 4000. I have 7600gt nvidia cards in SLI. I have 1 Gig of memory. My 3dmark 06 score is 3640 in sli and 3091 in single card. Thats only about a 15 percent increase. Is anyone else getting similar scores? I have downloaded the latest drivers.

 

I just ran a 3181 with a very similar system
(Not bad for a spare parts Build, next step OC the Snot out of it )

DFI NF4 Ultra D
Athlon 3500 10x240 at 2400Mhz, Water Cooled:drool
2x512mb Samsung TCCC CL3 memory (the memory running at 200FSB (5/6 divider I thinks)
A single XFX 7600GT XXX, stock 590/800, default setting's with Forceware 91.47 drivers, Air cooled for the moment

Looks like running a pair in SLI you should be getting over 5000 3dmarks you can see for your self at Futuremark http://service.futuremark.com/orb/resultanalyzer.jsp?projectType=14&XLID=0&UID=7486768
