Gtx 780 Ti

[gonzo72]

Hello,

I currently have an OC i5 2500K (running somewhere around 4,300) and my PCI-E slot is 2.0 x 16. Would the fact that the PCI slot is not 3.0 cause a 780 Ti to under perform?

I read a post where someone had subpar benchmarks with his card and some suggested this could be the cause. I returned a Sapphire Tri-X 290 since it did not seem to run consistent and I was getting artifacts in some games. I am currently thinking about just taking the plunge and going with a 780 Ti, but not if the rest of my system will bottleneck it.

PCI-E 2 and 3 perform the same, also your system should not bottleneck the GTX 780ti which is one of the most powerful GPU's on the market.

no, pcie 2.0 is not going to slow the 780ti down at all. the 2500k is still a beast so your good to go for the next 3 years no problem. my 2500k/780 have no problems hitting very high benchmarks with high overclocks and nothing is slowing anything down.

Agree with others, a 2500k, especially overclocked, will not be a bottleneck to pretty much and GPU setup out there currently. Same with PCIe 2.0. 2.0 will probably only begin to be a slight bottleneck when the next generation of GPU's come out.

Nikoli707, you really think an overclocked 2500k can last another 3 years? I hope so, but I have one at 4.4Ghz and was thinking of getting a new CPU and Mobo once DDR4 comes out....maybe I just have the upgrade itch lol.

Thank you for the replies. I did some more searching as well and found benchmarks that say the same thing. In some cases 2.0 was even faster, but they were always within a frame or so of each other so real difference.

Read it first on a post on the overclockers.com forum (I think) and wanted to ask here since it seems like there is always good advice given

since sandy bridge k processors, ivy and haswell are only minor improvements. intel is going to have to release a "sandy bridge" event with a near quantum leap in cpu performance jump like the 2500k/2600k were. at the time for $300, nothing could come close to the 2600k@4.5ghz, it was so powerful and unprecedented and easily compared to, in many cases surpassed, the previous gen $1000 extreme i7/xeon processors performance wise that it made them look like a joke. the 2500k was just a step below without hyperthreading which most people dont need and/or gaming wasn't seeing any benefit at the time.

i just dont see intel doing anything like that in the near future, at least until amd can release something that actually competes on the same performance level as a 4670k/4770k, or whatever the new gen is.

also unless your gaming with a $500+ gpu, or encoding, rendering or that type of work, >99% of computer users do not need that type of horsepower. most cpu manufactures are trying to figure out die shrinks and power efficiency now for handheld/small form factors, massive core performance is not their main concern.
