Update:
EVGA Tech support said the Core 2 Duo Q6600 that I have is being bottlenecked by the GTX 460 and there is really nothing I can do about it
. The chip has a FSB of 1066mhz and that aint enough. Sooooo, I just got 235.00 richer for the return and will re-install the GTS 250, 1 gig video card that I should never have replaced.
The Changeup Family always does stuff the hard way...that is all...dismissed.
Changeup
In an eariler post the mobo was a 680i board. The 1066Mhz FSB of the Q6600 is stock which would put the mem bandwidth (speed) at 533Mhz, right? Could this be the issue w/ a Fermi? On other BBS's users that were using the Q6600 w/ a Fermi vid card had the chip/mem OC'd (FSB clocked at 1333 or higher w/ subsequent OC of mem) & some of them were using the 680i mobo most likely w/ a BIOS update (this part is assumption, not fact).
I am currently running a GTX 470 SC on a 780i FTW mobo (std FSB is 1333) using a C2D E8600 CPU (std FSB is 1333) w/ 4Gb PC8500 DDR2 mem (std speed 1066 Mhz) w/o any issues. My FR stays between 55-60 FPS. I do have my E8600 OC'd (FSB up to 1600 from 1333 w/ multi at 10x =4.0 GHz ) but all else at stock settings/voltages/timings. The 470 runs at 57%-68% GPU usage approx 98% of the time while in-game w/ all graphics on maxed but shadows set at 4096 for preference (have run w/ 8192 shadows but scenes are darkened from it). IMHO if the Q6600 would have been OC'd (FSB at 1333 or higher w/ mem also clocked up to 800 or higher) the 460 would have behaved better notwithstanding the PCI-E 1.0 spec lanes.
This info don't mean nothing now since you've refunded the 460 Changeup but may help some other user that has a 680i mobo & is thinking about getting a Fermi vid card to run on it.
Just making an observation.
