I'm having some issues with a SLi setup with two 8800 GT 512mb. Performance increase is only about 5-10fps in games like Crysis, COD4, UT3, and the image is "jerky", like the fps isn't dropping but its "jerky" anyway.
When running S.T.A.L.K.E.R Clear Sky, the game runs so jerky, it gives me a headache. 3dmarks 06 reports no sli.
I'm wondering if the PSU is up to the job, both +12 rails have 34A combined. When I try to change the speed of the second cards fan, it doesn't change?? When overclocking both cards (same) the system goes even slower!!
System spec is;
AMD Athlon 64 X2 Dual Core 6000+ 3.00GHz (Socket AM2)
