GPU Bottleneck with this CPU?

Hi,
I have a AMD Athlon II X4 645 3.1 GHz
with an AMD Radeon HD 7870 Ghz edition

When I play Skyrim and I look at my GPU usage on MSI Afterburner its like 50%...
When I play Far Cry 3 its like 80% usage

My question is is my CPU really not good enough for my GPU? Am I being bottlenecked?

Thanks for replying I just don't understand shouldn't a quad core 3.1 GHz (I have it overclocked now to 3.4) is bottlenecking. Shouldn't this be good enough?

Athlons weren't meant to be gaming processors, and if i remember correctly, the lack of an l3 cache really hurts them too.

Is that a first gen PCIE interface? If so I'd say that's where the Bottleneck is.

Oh... So should I upgrade? And if so what kind of processor is good enough? Im looking more for AMD not Intel

FX - 8320 are good enough :D

He means pcie 1.0 slots. If you have a pcie 1.0 slot vs a 2.0 slot, it could hurt.

If i remember correctly, 645 are AM3. AM3 mobos have 2.0 slots.

But yeah the 8320 is a nice upgrade from a athlon 645

Well my motherboard is fairly new. Yeah it's a 2.0

Thanks I guess I'll start looking for a new CPU

Your board must be AM3+ for the cpu. or check your mobo's compatibility if it supports the FX8320 :D

Skyrim is pretty much single threaded so performance will depend on single threaded efficiency of your processor. I would recommend an intel processor if fps is really important to you, they have much better single threaded performance. A 4670k is a pretty good choice.

I dont have a intel motherboard though and I really don't feel like switching

for skyrim, yeah, major cpu bottleneck. will be bottlenecked with anything but an overclocked 6 or 8 core amd cpu, if you had intel any i5 would be good enough. you might have a 3+ghz quad core, but not all cpu's are created equal. a 3ghz current gen i5 would be twice a powerful for gaming as your athlon x4.

I'm kind of on a budget do you think this one would do the job AMD FX-4130 Zambezi 3.8GHz

Maybe consider the 6300 if its around 110$ or if not maybe if the price difference isn't too big, consider the 4300 over the 4130.

The 6300 should. The 4300 might need to be overclocked to fully solve the problem.

looks like a 4300 or 6300 are the best bet. 6300 would give best results overall, especially when overclocked. Skyrim just doesnt use AMD cpu's very well, you can see a dual core i3 outperforms an 8 core amd.

Honestly, if you are really into skyrim, I would save up and get intel. You can get a very good proc (4670k) plus motherboard for a little over $300. You're going to get minimal gains in gaming from an amd processor. I really do wish amd could provide more competition to intel, as I was using them up until my latest build. To that end, if skyrim isn't the biggest deal, you can get significant advantages in other games and applications that can take advantage of those extra cores on amd systems. If this suites you, you will be more than pleased.

Yeah I'm kind of into Skyrim but I don't think it's enough to spend more money on a intel CPU. I just have to deal with it. I mean it's not terrible. And it's just Skyrim right? I should see performance gains on other games?

It really depends on how the game is designed. If the game is a single thread heavy game, then you might not see a huge performance gain. If its a multi threaded game that uses all of your cores, which is what next gen should be optimizing for, then you might see performance at par or maybe some gains. AMD cpus are generally used in more of a budget build anyways.

Okay so is the processor good for the money im buying it for?

Yes you will always get good performance for the money with amd. As Calnin said, you will see better performance is multi-threaded games. Since all next gen consoles use amd hardware, games should work good on your.
