HD 7870 and Athlon II X3 455 3.3Ghz

Will my CPU bottleneck my GPU? Please speak from EXPERIENCE or FACTS and don't just say crap like "LOL DERP it's not intel so yes".

Will my CPU bottleneck my GPU?

Really depends on individual game,

Have you tried to unlock the 4th core in bios?

My current Mobo doesn't support core unlocking sadly. Thanks for the links. That Battlefield 3 comparison is pretty shocking. Shows how games should perform when a company puts some dedication into the PC version.

BF3 runs great in single player but multi player really needs the amd 6/8core or intel i5 quads.

Ok. I'm probably going to upgrade to an FX 8350 in the next few months. Would the 8350 combo well with the 7870?

[Nosferatu Jonas]

The FX 8350 is a nice CPU for the money, No prob with the 7870

if your board doesnt support unlocking i doubt it will take a fx 8000 cpu
instead get the 3570k and a z77 board, it wont cost much more

Yeah I know that I'd need to upgrade my mobo as well. I guess I could try a switch to team intel...

hmm.. It really depends. Bottlenecking Is a complex topic- for example, If you maxed out some of you other specs other than CPU, and compared It to a PC with the same CPU and low ram, slow HDD, etc, you would definately see a difference.

It can also depend on how you allocate your resources on that PC. PCs that are tweaked to run few programs at a time and disable the majority of their startup resources through msconfig will have an easier time running the core programs that they want to run at the expense of taking a little longer to first time load some of the programs that arent in the startup que.

In reality there is a plethora of things you can try and tweak first so that your PC /CPU process information more efficiently. Though this is not necesisarry an excuse to keep from upgrading, there ARE other things you can try before you upgrade to better CPU

Not complex at all, old news any way.

I recommend the FX 8 cores.

I think the HD 7870 is a smart choice and would recommend as high as a HD 7950.

Your CPU and Motherboard may both bottleneck the GPU slightly but it should be ok.

Since you plan for a FX 8 core later just consider the GPU a investment for now.

It also might not bottleneck it. I do not really know. It does have PCIe 2.0 right? So it should be fine.

What I do know is that always my HD 6950 gets used more than my FX 8150 by games even though it scores 7.9 on WEI while my FX 8150 scores only 7.8. Games love GPUs.

You might see a game using 50% CPU and 80% GPU even with your current setup.

switch to team intel
get an i5 instead of the fx8000s
the prices will be about the same and will do much better with programs that do not use all 8 cores

[Soylent_Merchant]

Yeah go ahead and get the Gpu as Rove mentioned, its not like it has an expiration date, and whether you go intel or fx youll have the gpu all ready to go

[VIPER5051]

i have and FX 8000 series and a 7870. they run well together but for games you really are better off going with an intel i5 or i7

[VIPER5051]

Intel is much better than AMD for gaming. especially considering games really dont use more than 4 cores. FX is good for brute power such as rendering. my friend has a rig very similar to mine but i5 with 7870. in the majority of games i have seen his rig runs about 20 FPS over mine. especially dayz where my rig drops below 20FPS and not over 30 whereas his wont drop below 30 and is usually about 45.
