There's a low CPU setting for slower CPUs. You can run a RadeonHD card on the Sam440-Flex by using a PCI-PCIe adapter.
Even a low end card like a 6450 gives a big boost in 2D pefromance and compositing so if you play games like MACE then you'll be able to play at higher rsolutions than before. See this video for a demonstration.
