Possible as it depends on the discrete GPU. IE any card upto the 6670 will crossfire with the A8-3850. Graphics wise you end up with about a 6730. Any larger tho I would suggest an i5 2400. I don't like suggesting the i3 as they tend to have higher latency. OS network processing must compete with FPS push for CPU cycles. Quad cores with under used cores tend to see less FPS loss and or lower latency. Another advantage with an i5 is the other programs you run will have less of an effect on FPS. Programs like VOIP, antivirus, and software firewall can all still away FPS on dual cores to a much greater degree than quads.
If you must go intel dual core I suggest the G860 as its about the same performance as the i3 but lower priced. Note the green bar is average being about .8FPS higher. The G850 maybe the best bang for the buck and price wise you can buy a comparable GPU to A8's.http://www.newegg.com/Product/Product.aspx?Item=N82E16819116405http://www.newegg.com/Product/Product.aspx?Item=N82E16819116397
