He means to say that the CPU will hold the graphics card back. He's somewhat mistaken in that, though.

You can get the 7970, but you should also take some time and overclock that CPU to increase its performance a bit. You can find tutorials on how to do this online. You'll also need a decent aftermarket CPU cooler for this. Looks like you already have that covered.

It means that if you put a 7970 GPU in this system and play games that depend on the CPU, your pretty weak non-gaming CPU will slow the game down even though the GPU can still give so much more performance if the processor had enough headroom to accommodate it.

This means that your hardware need to be balanced, GPU and CPU, in your current system, your CPU is good enough to drive the 7770 that you have, but if you want to utilize the full potential of the 7970 card then you need to replace your CPU with an FX-8350 since you already have an AMD system. By doing that your CPU/GPU will be balanced and in good standing to handle one another, and your GPU will be able to give you as much FPS as it can.

So you mean that instead of me waiting for the 4770K Haswell CPU that i am waiting for, that i should instead get an FX-4300, Overclock it with a decent cooler, stick a GTX 780 in there and be able to enjoy demanding titles while saving a bunch of money and an extra week or two of waiting?

So all that Intel i5 & i7 K version gaming CPUs and the FX-8350 are all just a big hyped illusion and everybody should start saving a bunch of money by getting an FX-4300 Processor for gaming?

I'm not saying that he - or you for that matter, should buy one. He didn't ask for help picking out a new processor, he already has the CPU and asked if he can get a 7970. Also people tend to think that FX 8350 has some sort of massive advantage over the FX 4300 when the only real difference between them in gaming use is increased cache.

Again not saying FX 4300 is better than 4770K or even as good as FX 8350. What I'm saying is that when overclocked, it's an all around decent gaming CPU and will not bottleneck a single HD 7970.

Have you checked this?

http://www.tomshardware.com/reviews/gaming-cpu-review-overclock,3106-3.html

graph_fx-4300.png


The above graph showing the performance of the FX-4300 in gaming, using the i7 as the 100% base performance scale, and it is clear that in titles like Skyrim is it bottle-necking the graphics by up to 35%, and no there is a huge difference between a 4300 CPU and a 8350 one, not only in terms of cache but also in the number of cores available to NextGen titles like Crysis 3 which seem to be able to utilize them to makeup for the poor per core performance of this architecture.

This will become even more important for NextGen games developed for the new 8 core consoles where games will be able to use all 8 cores to make up for the slow per core performance.

Based on all of the above the answer to the OPs question is, YES the FX-4300 CPU will technically bottleneck that high end GPU that he is intending to buy and if he wants full performance of that GPU then the processor he has is no good.

Yes it would work but will still BOTTLENECK the GPU like i said. how is that a "load of crap"?

PS: my i5 3570K @ 4.2Ghz and a 7970 card gets above 80% utilization during Crysis 3 gameplay, i would only imagine then that the FX-4300 will be 100% utilized on all cores before the GPU is even able to fully output all the FPS is can in this title, how is that not bottlenecking?

Still i wouldn't pair a 7970 GPU with a 4300 CPU if i want to get the full performance of that GPU, this is simply building an imbalanced system.

i would upgrade my CPU first!

You are just giving him a bad advice and i believe that he will be disappointed after he makes his purchase based on the promise that his 4300 CPU can handle that high end GPU he is intending to purchase.
