So when i built my first computer i wanted to do something different and the APU+Dedicated card intrigued me. I am currently running the a10-5800k with a 1 gig gddr5 6670 in dual graphics mode. In the few games that support it, it works beautifully and adds about 30% fps boost vs just the card. But the games that work well with it are few and far between. My questions is how much of a bottleneck will it be to get a $200 card like the radeon 7850 to put in this system to replace the 6670? My other thought is if i get a coolermaster hyper 212 as well and get the a10 to a stable 4.5-4.6 ghz (which seems very doable if you believe youtube), how much of said bottleneck do you think that would alleviate? Or should i just spend that $230-$240 on a better CPU(amd FX or intel i3-i5 is a whole other matter) and motherboard and stick with the 6670 till i can afford a better one 6 months down the road(got my first kid on the way so not very much "me money" anymore)?
