my old system dell xps 720 had an 8800 ultra and an Aegis pyshics card which I removed as the 8800 did the pyshics and Nvidia latest driver arent compatible with the Aegis card I replaced the 8800 with a gtx 570 with the 8800 running pyshics and was pretty pleased with the result, unfortunately the poweer supply blew and as Dell no longer made the PSU I went through insurance and have got a XPS 8500 with a AMD 7900 series GPU.
Would I be better off running my previous video setup in this new box or would the Aegis card and the AMD GPU give result. I output to a Samsung 51" 3D Plasma via HDMI.
What do you guys think is my best bet
The Aegia PhysX card is obsolete. If you want to run PhysX games with an AMD card, there is a hack to make it run (do a google search "AMD physx hack"). The alternative would be to install your two Nvidia cards, which are a good pairing and still provide good performance on all the latest games.
