[arch-general] New 64 bit computer

I am gathering info on this new system I just bought a new computer ($550USD complete) as I wanted to go 64 bit Gigabyte GA-MA770T-UD3P motherboard AMD Phenom II X4 810 AM3 socket 2.6G 8GB High performance DDR3 ram Radeon HD 4670 Will arch 64 install and run on this? With little trouble? :) I am concerned with the ATI video card, Any problems with this card? What can I expect running Arch 64 on the system? Now I can make many more errors only twice as fast :)
