Also, the graphics card I want to update to has a pci 3 port and i don't believe my mobo has that. How much performance would i lose putting it into a pci 2 port?
Well upgrading the CPU from an 8100 to an 83XX will improve performance a little because the first generation FX processors (41xx, 61xx, 81xx) aren't really an improvement over Phenoms II. So look into an 8350.
Graphic ports (PCIe) are backwards compatible. You can place any PCIe 3.0 GPU in a PCIe 2.0 port without suffering performance loss. PCIe 2.0 actually hasn't been fully utilized so it's likely that motherboards that support Crossfire or SLI actually have similar performance to PCIe 3.0 boards. You'll be fine. Don't worry about that.
You even have a decent PSU. So upgrade away.
Edit: I forgot to add, before you pop in a new PSU, check the BIOS version of your motherboard. You may need to update it to support the second gen FX processors.
