I have an A8-5600K and have successfuly CrossfireXd it with an HD 7750

Graphics performance uplift to -

314%  vs  A8-5600K solo

113%  vs  HD 7750 in discreet mode  (i.e.,  the iGPU is disabled)

 

 

Just comparing HD 6670.  The est graphics performance increase using the official Dual graphics pair HD 6670 will only yield -  Click here

173% vs  A8-5600K solo  

 

 

This HD 7750 dual graphics performance is comparable to the following discreet video cards -

  • equal to HD 7770
  • +15% better than GTX 650

 

 

I am on Catalyst ver 13.9  and  Win 8 x64  

Mother board:  Gigabyte A85 mini-ITX

Video card:  HIS HD 7750 IceQ X Turbo 1 GB GDDR5 

 

I don't want to sound bragging about this but just wanted to share to others who might be considering the upgrade

 

Here are my 3DMark11 tests results :

I've pre-orderd BF4 and this weekend,  I took time to tweak my rig further to get it ready.

 

I've adjusted the integrated GPU HD 7560D from the default 760 MHz to 900 MHz.  The latter matches my factory overclocked HD 7750 which is at 900 MHz

 

Dual graphics performance have increased further as a result  -  Click here

325%  vs  A8-5600K solo

117%  vs  HD 7750 in discreet mode  (i.e.,  the iGPU is disabled)

 

I have also updated my data in my earlier post above above based on further 3DMark11 tests

Do you guys have trouble with stuttering, screen-tearing or runt frames? I've heard people were having issues with it in that regard.

I also have a8-5600k and hd 7750. But, I don't know how to do the crossfire / dual graphics mode, I can't see the crossfire option in Catalyst 13.12. Can you please tell me how did you do the crossfire mode? :'(
