do you think its worth it to have 8800gts for physX purpose ??
I tried using my old 8800GTS with my 5870 for physx. I wanted to see if it worked for Batman, so I got the nessesary drivers, hacks and a good tutorial from youtube and gave it a try but found out that its very messy having all those drivers in your system and it gets hot! Lots of video anomalies and crashing! plus its better to use windows 7 because vista doesnt allow you to use the hack.
Thats why I said that its not worth the hastle.
Then again some people have not experienced these issues and are ok with it!
