Bottleneck Question

[Tekt]

Hello,

I have an i7 2600k CPU OCd at 4.4ghz. If I were to upgrade my video card to a more current nVidia card (770, 780, etc), would I have any kind of bottlenecking issues?


I appreciate your responses.

You will face a bit lower than expected performance because no pcie 3.0 on sandy chipset, unless your mobo is on the ivy platform for some reason

I dont think thats even noticable.

Yes, my board does have PCI Express 3.0 support/Ivy compatible as I've had to replace my old motherboard.

Then there's nothing really holding you back.

What is the performance gain with a Haswell over an Ivy CPU anyways?

around 10-15% though u have to keep in mind that haswell runs much hotter than ivy and u will spend some extra on better cooling solutions..

Over an Ivy or over a Sandy? Yours is sandy.

Performance gain clock-for-clock (which for overclockers is a silly comparison) is I think 10-20% performance increase (Haswell vs IVY it is a bit more against Sandy). Haswell is much more of a silicon lottery but delidding (high risk, high reward) can make haswell very strong. The Z87 platform is a bit nicer to work with as it has all SATA3 ports and I think the motherboards aesthetically look a lot better. It also consumes less power if that matters at all to you.

For most people with a 3570k/3770k, they have no reason to upgrade.

People who just want to play games at high/ultra haven't felt the dire need to upgrade from their 2500k/2600k yet, either.

Not that much. If you go from a 2600k to a 4770k (both on stock clocks), the benefit in cpu-intensive things is about 10-20%. Overclocked the difference is less, because Haswell does not overclock very well without de-lidding (= voiding your warranty). And additionally the benefit in games is even less, because most games are gpu-bottlenecked rather than by the cpu.

Thank you.

I was wondering primarily because I didn't know if it would be worth it yet to upgrade CPU from Sandy to Ivy, or even from Sandy to Haswell (which would require a new motherboard). If I were to buy a new GPU I was curious if I should go all in and get another new board and a new CPU. I suppose I could just get the new GPU (if necessary) and see.

if u can say that 20 % isnt much
