I was wondering if anybody has any thoughts on using one of the new AMD A10 Kavari chips to both run the system with the CPU portion of the chip and mine using the GPU portion of the chip along side your physical GPU cards? Cost would be some consideration, because extra money going into the purchase of the APU v. cheap chip could be put into a physical graphics card. I know Newegg has these chips on hand:
http://www.newegg.com/Product/Product.aspx?Item=N82E16819113359 with a cost of $189.99 and 95 watts for R7 series graphics performance. Compare that to the $49.99 cost of an AMD A4-4000 @ 65 watts to just run your system? That's a $140.00 cost difference and if you compare that to the cost of some of the R9 270's that could be had for $199.99 (Newegg). It's just a thought and something I was kicking around.
