Getting an AMD system going is not that different than doing so with an Intel system. First crucial detail that applies to both, is that you should run the CPU builder's chipset. So the fact that the OP's PC has an Nvidia chipset on the mobo is a good indication that the system will be problematic. While there is a lot to do with wether or not certain components will work together, the most important thing for PC users is to properly tweak and optimize the BIOS and Windows install. If this is too much trouble or just simply something people don't want to deal with, which is totally understandable, then buying a Mac is not a bad idea. You still have to optimize your Mac, but you may not deal with all the trial and error stuff that goes along with a Windows PC.
