well... this is simple, i wanna tell how good is to use a second card as physx, in this case i use my old 9600gt as physx card, and the improve was very big.. i played UT3 using only my 9800gtx and also playing in the physx maps, everything at max, and 1440*900 res.... and my fps was about 12/16 (very low) and when i put the second card the fps increase was big, i mean, it jump to 55/58fps with same settings.. i will put the results here...
This is what Ive been waiting for... a comparison to see how if a better physx card makes a difference....it looks like I am keeping my 8800gt KO from this early report.
