I would say that this build would likely last without an upgrade for at least a couple of years. That said, it's an easy build to upgrade. The board supports Crossfire, so you can stick a second 5850 in it. The case is big enough that it can fit larger cards if you go that route. The motherboard also supports USB 3/SATA III, so it can last for a while once the newer drives and devices once they come out. Also, it will support future AMD CPUs as well, though you might have to upgrade the BIOS.
