Hey... I was wanting to know if this PC can have a Ageia Physx Card I was thinking of adding one the next time I add stuff to it its more of a general Purpose Pentium 3 but games that use Physx could run because it eases the Preasure on the CPu some gamesa that I woudl run with it in the Future. -Rail Simulator (release Q2 2007) Developed By Kuju Uses Physx to ease the Pressure on the CPU. The PC curently is cheapo but some upgrading will give me a Resonable PC Currently, 145W Micro ATX PSU DVD Burner Built in INtel 82815 GPU 20gb Ultra ATA/100 HDD 933mhz CPU Intel D815EFV Mainboard 2x256mb Pc133SDRAM 50ns= 512MB @ 133mhz.

After Upgrade it should have 400W Micro ATX PSU Radeon AGP 9600PRO 256mb 20gb+160gb Ultra ATA/100 933mhz Intel Pentium 3 with High speed 256kb Die-On Chache. 512mb Pc133 Ram Those are for sure but I want to add a Physx aswell but can I the mainboard has. 3x PCI 2.2 Expansion slots Are the slots the right ones and will the specs after the upgrade do it?
