The cards are not the issue. Drivers can be problematic with certain workloads (like rendering UIs) and not others (like loading and running non-graphics programs). It's also a lot easier to debug and deploy a fix to a farm of identical servers with identical drivers than it is to be compatible across a huge breadth of configurations.
