So question is pairing say a 7850k and a 7970 better than pairing a 7970 and a FX 8350 or something? Linus kinda left these question unanswered in his latest video as he only tested CPUs with integrated graphics on them.

Most modern games don't really use the CPU. You'll get a bottleneck but how much is the question. That is something I don't think reviewers have looked into.

Not going to work. As the guy above said you can only pair that with a r7 250 at max. It'd be better to get a 8350 along side with a 7970.

Wanna hang out with me and people like @Theslsamg, @ Ssoele, @BENTHEREN, @Lanoi, @Whiskers, @_ASSASSIN_, @Looney, @WunderWuffle, and @nsyedhasan. Well.... Check out: http://linustechtips.com/main/topic/48484-unofficial-linustechtips-teamschnitzel-server-teamspeak/

Ahhhh so you can only pair with certain GPUs i didnt get that from the video, whats the most powerful card you can pair with atm?

The r7 250, thus it is not worth noting outside of very certain circumstances. In general unless you have an absolutely non negotiable budget getting a solid cpu + best discrete card you can get while keeping the cpu / gpu balanced is the way to go. If you ever have questions on a new build the planning sub forum is great.

Only low end stuff. If you have the budget get a dedicated GPU with a CPU you can afford.

If you don't have the budget, then wait. If you are impatient get an APU, upgrade later.

HSA, if and when it's supported, would let you at least get some benefit from the GPU in an APU with a higher end card though, so I wonder what that will look like. If HSA is popular enough, theoretically they could resolve a lot of the CPU bottlenecking that would occur by using the integrated GPU for physics and such. However, I don't know if that will really be that much better than just having twice the cores. If we start getting 6 or 8 core APU's though, and HSA or OpenCL or something takes off, that could be an interesting set of benchmarks.

yes they do. bf4, crysis 3 and many more they even used most of the cores on cpu's now.

More cores doesn't mean it is a more CPU intensive game.

 

Skyrim benefits highly from a more powerful CPU and is very single threaded.

 

More threads just means it will take advantage of more cores but doesn't imply any more workload than it would be if it was one thread. It's just being handled more efficiently.

Go Kaveri and overclock it. FM2+ is a much nicer platform too.

 

I doubt it'll bottleneck that much if at all. Less of a bottleneck in lower threaded games than FX :D
