Hey, so I am building a budget pc build for my brother and I am planning a mini-itx build. After browsing motherboards I found that the only ones that fit in my budget had a PCI-E 2.0 slot. Will this affect performance as opposed to a PCI-E 3.0 slot?

The effect would be unnoticeable.

What about for something like a 750ti?

Not at all. Even flagship single GPU cards aren't maxing PCIe 2.0 8x yet.

That should be alright, what chip-set / processor are you going to use?

Thanks!

I'm planning a pentium G3258.

PCIe 2.0 is fine; I forget where I read it but when 290xs came out a couple years back, AMD and a couple of other 3rd parties did some testing; 2 290xs in Crossfire(which didn't use a bridge so it should use extra PCIe bandwidth) weren't shown to have any noticeable difference between PCIe 3.0 and PCIe 2.0 even with PCIe 2.0 8x mode for each gpu differences were within margin of error of 16x/16x PCIe 3.0

In that case, the only thing holding you back from seeing what the card is fully capable of is your processor and motherboard basically.

 

I know from using it right now, I have identical cards in this pc and my gaming pc. One is 2.0 and the other is 3.0. This pc I'll maybe get 30-40 FPS. Other pc I'll get 80-100 FPS.

 

It can depend on your CPU and motherboard combo.

Thanks!

Well, this is just a low cost build for my little brother (hes 10) who just wants to play Euro Truck Simulator and Minecraft. I know the 750ti is a bit overkill for these games but it fit in the budget so what the hey.

PCIe 3.0 would get you 2-6FPS at max
