Is it true about H & Z series chipsets?

Is it true that a single Nvidia or AMD GPU performs better on a Z series motherboard and performs less on H or B series motherboards regardless of OCing or anything just on stock im asking?

Actually i recently bought some new PC stuff like i5 4670k, CPU Cooler, Case, HDD etc and currently ordered ASRock Fatal1ty H87 Performance motherboard and waiting for it's delivery in this week. My friend forcing me to buy Z87 board and saying that cards like GTX 760 will not perform good on the board i ordered even on stock.. problem is the 4th Gen boards are quiet limited here and expensive almost double the price of H series unlike Z77 which are quiet affordable but only supports Sandy & Ivy's and Haswell has a new socket 1150. Also previously i was on LGA 775 and this is gonna be my first i5 desktop system! and now i want to have the latest system.

I don't see any reason the performance should be any different on a H board compared to a Z board using a single GPU with the same CPU at stock. Both would be using PCI-e 3 at X16. So in theory the performance should be identical.

that's exactly how i think too paulpicks when using single gpu and on stock even if the cpu and gpu are overclocked on same clocks so they should technically perform eqaulant

Can you overclock on an H series motherboard?

It has/is being locked out on the new Haswell ones Kelly - Intel updates microcode to block H87/B85 overclocking | bit-tech.net

But in the original post we were talking about stock speeds not overclocked.

OK. If you have a 4570K already, why not get the full potential with a Z87 motherboard?

He kind of put that in the first post Kelly, they are limited availability where he is and almost double the price.

I guess it's a budget thing, but then maybe it would have been better to go for a non K series CPU.

Well, if they get an H series board, and then realize later on they want a Z series board so they can OC, they aren't saving any money. Also, there are plenty of reasonably priced Z87 boards from Asus that have what you need and use quality components. I really don't seen any point of an H/B series board with an unlocked CPU.

I totally agree there Kelly, it defeats the object.

But I am waffling on and this has moved away from the original question.

Back on topic then. A single video card will perform the same on either series motherboard.
