can a motherboard bottleneck a cpu?

post #1 of 6
Thread Starter 
Can a cheap mobo bottleneck a cpu? You are probably thinking of my current system with g41 board,but I'm not worried about that. I'm thinking of getting a 2600k SB with a ~$100 mobo (I'm on a tight budget) and was wondendering if it will bottleneck the 2600k at all? (I'm thinking of p67a-ud3). As of right now I see very low scores on my system with 3dmark vantage and 06 , and I think it's because of my cheap mobo.

Thanks:)

If you don't plan extreme OCing, I could say NO.

Yes I am necro-ing this thread, but I would like an explanation from more than just one person if the OCN community doesn't mind. wink.gif

If you have an 1155 micro-ATX mobo with a single PCIe slot and two RAM slots.... Couldn't you theoretically run a 2500k with a GTX580/590 and 8GB of G.Skill? Wouldn't that still be a pretty beastly gaming rig? Or would the cheap mobo (to use an overused word) bottleneck your system?

In theory a motherboard could bottleneck a cpu but i don't think with ANY motherboard on the market would.The tech we see today in the current boards is far better than what we seen 5 to 10 years ago.To answer the OP's question,which is a old thread yes it would work fine.You can take a cheap mother board and it would not bottleneck it.It might not give the overclocks a better board can give but bottleneck NO.

I was also wondering this same thing. I got a 2500k with a budget mobo (msi p67a g43 (b3)) and I was wondering if it would bottleneck my cpu. I know of people that can get their 2500k's with my mobo to 4.5ghz so I don't think it will bottleneck it but I'm not sure.
