I intend to buy an AMD A10 7850k + R7 250 1G DDR5 (Configuration in crossfire) 

I would like to know the equivalent in graphics power of this type of installation (iGPU + R7 250 crossfire) 

It is as powerful as R7 260X? R9270? 

Thank you for your answers

Short answer: NO.

Performance increase with AMD Dual graphics (IGP + Discrete Graphics) is not going to be as great as using higher end discrete R7/R9 cards.

You can take a look at reviews on Youtube and other sites. My personal setup is AMD A10-7700K + R7 240 2GB GDDR3 (eff: 1800MHz) - real world perf: Battlefield 4 at 1080p 60Hz is on LOW settings: average 20-35fps (no overclock for both IGP and R7 240).

Using AMD Overdrive - with IGP 800MHz and R7240 850Mhz, I had about 25-40fps. My RAM is DDR3 1600Mhz, maybe you can get more with faster DDR3 system RAM.

Your new setup would be at least 5-10fps higher than mine.

Software:
OS: Windows 8.1 with 8.1 Update
Catalyst: 14.4 (WHQL)
Battlefield display driver: Mantle
Multiplayer mode

Hardware:
APU: A10-7700K - Main GPU
Sapphire R7-240 780Mhz 2GB GDDR3 900Mhz - Secondary GPU
ASUS A88X-MA
Corsair ValueRAM DDR3 1600

Note: Cannot set the output/main graphics to the R7 240 with the Catalyst 14.4 due to driver issue.
