Possible Bottleneck Issue?

Will an AMD FX 6300 @ 4.0 ghz OC bottleneck a R9 290? R9 280X ? Looking to upgrade from a 7870.

Also My main rig is an AMD FX 6350 @ 4.2 ghz daily and 5.0 for gaming. Am I wasting my 780 TI in this rig?

play the games the way you want to, ie. resolution, settings and fps and see if the CPU is at 100%. If it is and your GPU's are notably lower, then the CPU is holding them back. If just 60fps, 1080p, then the GPUs are already an overkill irrespective of the CPU.

The 6300 will bottleneck, period.
The amount depends on the game. A 7870 is a good match, which games are you trying to play?

In order to use that 780 ti properly you need to jump to an intel setup.





 
Remember, every application has it's own unique performance demands. Also not everyone's rig is the same, and neither is their monitor. All these factors make it impossible to generalize any "bottleneck" so if you read someone randomly throwing the term "bottleneck" around without knowing your system specs, your monitor specs, and what application you are running you should be very skeptical of their advice.

Just a couple of points:

We CAN make bottleneck generalizations, because we have many benchmarks from a lot of sources to draw comparison data from.

A pentium 4 or an amd apu are generally a bad idea to pair with a gtx 780/r9 290 etc. etc.

Also "THW is always in need of bottleneck explanation" could be taken the wrong way, might want to reword it a bit.

These are both CPUs not trash apus. They are ranked 2 and 3 on TOMS hiearchy chart respectively when stock. Both are significantly OCed. Since my OP i checked out the 780 TI on the fx-6350 with Unigine heaven and 3D Mark Firestrike and it is scoring well above the benches on TOMs charts for the same card at 1080p. I think I answered my own question. Zero bottleneck :bounce:

Benchmarks are nice, but how about actual gaming?

A 5ghz 6300 isn't impressive, it takes a 5ghz 8350 to even start to match a stock xeon 1220v3 for example.

Like I said the bottleneck will always be there, depending on title it can be slight or it can be large.

Planetside 2, or watch_dogs.

In fact since properly threaded games are so rare you are actually bottlenecking most of the time while gaming with your setup. Just look at how a 8350 compares to a stock i3.


Seems kinda silly to ask a question and then toss the answer when you don't like it.
 
Even the i7 "bottlenecks" in those poorly coded games ^^

My lowly Athlon doesn't bottleneck Skyrim or BF3? 60 FPS no dips. It all depends on the game. People that throw out bottleneck generalizations should really read "Bottlenecks for Beginners"

You said no bottlenecks, I just proved you wrong. There are MANY games that run this way.

Watch dogs is a peek at things to come, cpu wise.

Indeed,look at the watch dogs bench, what does the 4ghz oc 965 do fps wise?


I loved skyrim, and upgraded my 3.8ghz 1055t just to play smoothly. Athlon? I kinda scoff at your claims based on personal experience and the multitude of benchmarks.

 


Scoff all day long. I'll be posting a video shortly.

If this game averages 32 fps on a 3570k w/ a r9=290x at 1080p ultra it OBVIOUSLY needs serious optimization. It is recently ported to pc as I recall.

And to answer your observation about tossing the answers. I really wish TOMs would give some more detail on how we users can run the same benches they do to test our systems against the metrics they post. I play a few games, mostly WOT, BF4, Bioshock Infinite, Diablo, WOW, dabble at some of the other current FPS games and some old sub syms.

Would love to be able to comparitively bench this the same way TOMs does on current games.

wow that dude is in denial haha, I know those older Athlon's is not that much a problem with skyrim, my fx 4300 and r9 270 60fps+ is too easy to do.... so really it doesn't sound that unreasonable it could do it easy.
 
I was pretty amazed myself that my Athlon 760K can handle Skyrim and BF3 (sorry those are my heaviest games installed at the moment for my sons).

Granted I have a hefty overclock of 4.5GHz CPU, 2.6GHZ CPU-NB, DDR3-2400CL10, and GPU at 1200/1500.
