Bottle neck worries

[Simply Tom]

I currently have a fx-8120(not overclocked at the moment) I will be upgrading to a gtx 780 from a 570 soon and I am concerned that my cpu might bottleneck the 780. I can get my cpu up to about 4ghz stable and I would oc it to go with the 780. Should I be worried about my cpu pairing with a 780 or will it be okay?

 

The rest of the specs for my system are:

RAM: 16gb of ddr3 1866 G skill Ares

MOBO: ASrock 970 Extreme4

Power: OCZ 700watt ModXSream-Pro

Heat sink: CM 212 evo

 

 

Thank you

A gtx 780 will be bottlenecked by the 8150. If you don't overclock it will surely be bottlenecked

I think even overclocked there will be some bottlenecking there. It's a bulldozer chip and they didn't perform all that well. A safer bet may be to get something like a GTX 770 or wait for the 760Ti if you are into Nvidia chips. Also to note nvidia chips are normally less dependant on CPU performance.

I was considering upgrading to the i5  Haswell but I wanted to know if it was necessary since it would be rather expensive.

Honestly given your platform and your motherboard update your bios and get a 8350 you can do that and it will be far more economical to do that then to change platforms and get a new mobo new cpu.

I already have the latest bios, but thank you. But if I am going to upgrade I am going to upgrade my whole system. I jumped the gun when I bought mine because it was so much cheaper than the intel solution. I would rather have a whole new system. I am also concerned about pci express 3.0 vs 2.0 for the 780, does it make a difference?

[Simply Tom]

Does anyone know how significant of a bottleneck I would expect if I put a 780 in my current system oc'd to 4ghz?

[calarahil]

At the current moment pci express 3.0 isn't a important thing. The bandwitdth of cards isn't taking advantage of the higher bandwidth least not yet so you should be just fine.

And thats fine if you want to upgrade to a new platform haswell is fine. I'm personally waiting for skylake which is after that. Mainly because haswell is more of a power saving chip interation. Where as Skylake will bring in DDR4 hopefully as well as more performance increases. I currently have a 2500k.

It's hard to say. I would say would it hurt your perfomance a ton no it will not. And the performance may be okay for you. Maybe that is the best advice I can give you. If you like the card get it if the performance is okay for now stick with it and when something comes out you want CPU wise that is a significant upgrade do that.

Thank you for the advice. I think I am probably just going to get the 780 run some test and see how much of a dip I am experiencing and then decide whether or not I want to upgrade my whole system. I did have my doubts about haswell because it seems to be aimed towards mobile more than desktop. Plus I want to get a 780 so that it will last me longer than my 570 has, 2 years.

[calarahil]

Yea typically the higher end cards will last you a bit longer the 7 and 8 in a series so I would say you should be okay for a little while. Not that future proofing is a thing but there will be strong value for a while.

I think you are going at it the right way.
