Technically Intel provides better preformance but we're talking about a tiny i3 vs the Rana 423 2.9 ghz x3. 3 cores vs 2? for gaming + there's a clear winner. And you're shaving about $55 off your budget.
You have to remember AMD's X6's match Intels i7 930, so one would expect their tri-core to equal or be beaten by the i5/i7 dual cores. AMD is the clear winner in price to performance, so on a tight budget... They are the BEST option.
