if you're looking for a good cpu with decent intergrated graphics and cheap, this is decent however there are many better cpus if you're paring with a gpu (btw I do know im 3 years to this question XD)
nope sucksssssssss
this processor sucks trust me , i tried it my self....sooooo full of crap
It wouldn't be crossfire, it would be amd dual graphics. I have it done with a hd7750, which is supposed to be the highest but you could try it, you need to go into bios and set your on-board graphics card to these settings. in gfx configuration set primary to Nb pci-e slot Integrated graphics to Force Uma frame buffer to 2gb (to get the best out of it) The most important thing is, you need a power supply 500w or better that is compatible with Amd crossfire and dual graphics. I went with a 600w to be safe the higher wattage psu is better because then you have ample power to run everything with no strain on the psu
AMD a8 6600k is good?
Wtf, 4.86 GHz on water? Mines running 4.8 on air, all four cores... ಠ_ಠ
i never did install drivers for my AMD 8570D, i just went straight and installed an EVGA GTX 650.... was that bad?
as far as i know a radeon hd 7750 is the highest you can crossfire with it.
Can I do crossfire with my hd 7850? because the a8 6600k have an 8570d graphics processor
