Thank you for reply.
I have two CyberPowerPC systems now, one the AMD and one now the Intel. I get the eVGA GTX 460 OC 1 gig with GPU at 763, Mem at 950 and Shader at 1526, factory setting and have very good air cooling for system and for CPU, to avoid problem with not big enough CPU fan or enough System fan in AMD system.
New system came with Window 7 Professional 64 bit and 12 gig 1600 RAM. Window XP was no longer downgrade option offered.
I post another thread about problems with Nvidia driver in games using Windows 7 and seek help there.
I think I made best value Nvidia choice, but am not sure if not AMD 5830 might be more stable and better working with Window 7.
I hope to find assistance from fellow members regarding it.
Thank you again for reply.
