Food for though would be to go with an Intel i3 2100 based build and use the IGP. Then when the budget permits you pick up an entry level gaming card. It will in turn give you a more powerful x86 CPU and an overall better gaming system with the dedicated GPU assuming you go with the entry level gaming card.

If you never plan to upgrade then by all means go with the A8-3850 but if you think upgrading can be in your future then the i3 system would make more sense since the upgrade path is far larger than an A8 system.
