Don't worry about synthetics. It's not a bad exchange IMO. The two would trade blows with the 9600GT taking higher resolutions or fsaa. The only out of the box 8800GTS 320MB that would top the 9600GT is the super high clocked XFX Fatality. Then you could still just OC your 9600GT if you want.
Compare the cards here (slow to load but packed full of data): http://en.expreview.com/2008/04/02/g80-vs-g92-hi-end-geforce-gfx-cards-round-up.html/13
Nice data chart, but neither my old nor my new card is on it. There are no OC cards listed there. The 320 listed is only 513Mhz and mine was 580Mhz. The 9600GT listed is a stock 650Mhz and the one they sent is a 675Mhz.
That said, It's all good now. I found the problem that caused the drop in score.
After I physically installed the new 9600GT OC 512 card I upgraded the drivers as well, then did the performance tests. I then swapped back with the other card I have(second of sli pair 8800GTS320 OC2). It got a low score as well. Not by the GPU, but of the CPU again. I was shocked, but considered the driver so i re-installed the old driver. It didn't work so I went older a couple of more times till I got to 182.50. BAM! Got my scores back! Even the 9600GT OC has an almost identical high score in aquamark(13,000).
SORRY... I meant 113,000
Still around 100 points less than the 8800GTS OC2 in 3DMark06 1.02, but I can live with that. Their lifetime warranty is awesome!!! If not for that I would be out a videocard. :0)
I do think COD4 was taking a hit in the fps department with the new nvidia drivers so I am sticking with the old ones till I see aquamark put out decent scores again on the new drivers. I know aquamark is old, but COD4 isnt. If both were negatively affected then there is something wrong.
I was told to call BFG if I didn't receive another identical videocard than what I sent back to re-complete my sli setup and they would get me to send back the working old one and send another new one identical to what they sent me. I did that and I have the new RMA# and even a shipping label giving me prepaid shipping this time! These guys are awesome!
Thanks guys for all the input on the matter.
PS: I get a pci slot back!! 2 with the second card! LOL
