sorry, current board is AM2 but can upgrade to AM3 with a simple BIOS update.  Was looking at either a CPU   
AMD HDZ970FBGMBOX Phenom II X4 970 Black Edition Processor - 3.50GHz, Socket AM3, 6MB Cache, 2000MHz (4000 MT/s) FSB   
or Video Card   
MSI R6850 Cyclone PE/OC Radeon HD 6850 Video Card - 1GB, GDDR5, PCI-Express 2.0 x16, HDMI, Dual DVI, DisplayPort, Directx 11, Dual-Slot, Overclocked   
My only restriction with my current MB is DDR2 memory.  I know I should just build a new rig, but until my wife gets a new job I need to focus funds on feeding the kids....seems they are addicted to food!
