Hi ,
I have Intel g 31/33 Motherboard
Intel core 2 Duo T6750 CPU
6GB of RAM
System works extremely fast when i use 32 bit of any OS
and extremely slow when install any 64 bit os(Win 7/ win8)
CPU usage shows 100 percent
tried disabling all the start up apps
and many services one by one checking perfmon/Task manager

Please suggest if i have to upgrade my PC / Board or i need a graphics card as one of my friend has same CPU and Gigabyte H 41 motherboard and ASUS NVIDia 1 GB graphics card and he can use 64 bit OS smoothly
