Hi,
I was wondering if hybrid cross-firing requires more than one monitor or am I able to use my on board gpu along with 2 external graphics cards... here is my info, thanks in advance.
mobo : M4A785TD-V EVO which has an integrated radeon hd 4200 gpu
cpu: AMD Phenom(tm) II X4 955 Processor
os: Win 7 ultimate
psu: i forget but more than enough to handle power consumption
planning on having 2 radeon hd 4670s with 1gb vram each would i be able to use those 2 with my integrated one and only one monitor for the graphics power?

The integrated only works with lower cards, will not work with the 2 x HD4670.

so if I already have one hd4670 is it worth the $40 for another? and would I still be able to have the 2gb of vram?

In Crossfire with 2 x 1GB cards the ram still counts as 1GB! I would say spend alittle more and get at least a HD6770 which will outperform the other two cards and sell or keep as spare the HD4670.

so the second hd4670 wouldn't be worth the additional power?
