I'm planning on waiting until the AMD 8xxx series releases, so for the time being I will have to run on the integrated Intel HD 4000 graphics. My question is, will the stock heatsink/fan be good enough to cool the CPU with the graphics enabled? And when I get the graphics card, will I be able to put it into the motherboard and the integrated graphics will just stop on their own?
yes, if ur not overclocking the stock cooler will do fine.
unless u plan on overclocking, than thats a different story, but in general id recommand u upgrade to a better cooler to start with, since heat puts more stress on a cpu more than anything and kills the linespan of it, its not obligatory but its a recommandation i give since intel cooler will work but doesnt give super temps,
if youd like something for u to overclock and play with at a budget price u cant beat the
If you're worried about your PSU supporting an aftermarket cooler, you should probably go ahead and change it, especially considering your 8xxx series card will require an upgraded PSU anyway. So start looking into a 650W PSU, give yourself some time to shop around and find one that best fits your budget/needs.
Just bear in mind, that when buying a PSU, you should be looking at the +12v rail. It should have at least 35 amps on it, or 40 to be safe.
thats wher ei would probably draw the line when the next series(whether it be 8000 or 9000, because its confirmed that oem 89xx are 79xx rebadges, so theres a slim chance it will be named 9k). For limit purposes, since the next set is just optimized GCN, i would recommend at most the highest single pin card(so most likely the 8850/9850 depending on however amd will name it)
