previously pcked the asus h81m-e motherboard. However after some serching, found that it has a PCIe 1.0 x 16 and a PCIe 2.0 x 1. Im planning on using a gtx 770 so the 1.0 is useless but the 2.0 only has one lane (as it is only x1) so thats also useless right? so i have the option of changing to a asus h87m-e which has a PCIe 3.0/2.0 x16 and 3 PCIe 2.0 x 1 slots. So this is much better than the first mobo and also compatible with my card right? or am i missing something.

Full specs for h81m-e are here : https://www.asus.com/Motherboards/H81ME/#specifications

and the h87m-e are here https://www.asus.com/Motherboards/H87ME/#specifications

so am i right in my thinking, or could the first board use this card?

You would be absolutely right in that.
The 2.0 x1 vs the 2.0 x16 for that card would be a big insult to your GPU.

Those are both solid mother boards. The H87ME will be the better choice because of the newer chipset, but i don't believe it will even make a noticable difference in performance.
The determining factor between those two boards will be strictly what are your upgrade plans?
Are you planning on doing an SLI solution in the future? If so, more PCIe 2.0 or 3.0 would suit you better.
Although, with any GPU now-a-days, i would not go any less than PCIe 2.0 x16, bottom line.
Any less than that, and you aren't using your GPU to it's full potential due to a bottleneck at the PCIe lanes.
My only other suggestion would be get a 3GB graphics card, due to the rising popularity in new games wanting more VRAM.
BF4 for example is 2GB recommended, since that is the game everyone is referring to right now.

Nor planning on sli or overclocking, its my first gaming pc but ill only probably use it for about 3 years until im off to uni, until then i think a gtx 770 should handle most games at atleast medium or higher. But as for the PCIe slots, wouldnt i be best of with the h87m then as the h81m only has a 2.0 x 1, the other is at x16 but is only a 1.0, where as the h87m has a 3.0 x16 slot, which would be appropriate for my card. Basically, getting the h81m would severly hinder the gtx 770's performance so im best of going with the h87m so it doesnt lower the performance? there is a z87m - plus motherboartd but i dont see the point in getting that as its for SLI which i dont intent to do

With that specific GPU, PCIe 2.0 x16 vs PCIe 3.0 x16, you will see no performance difference.
Ultimately, that card (as well as almost every card out today) is not fast enough to saturate the data bandwidth available on a 3.0, and aren't quite maxing out the 2.0's.
You will literally see about a 1% increase in performance from a 2.0 to a 3.0 with that card.
Getting a MOBO with 2.0 will save you on some cash, but a 3.0 is more "future proof".
So between those two, i would go with the H87ME, hands down.
Try and find some benchmarks with those MOBOs and see what you find!

yeah, well the h87m-e has a 3.0/2.0 x16, where as the highest that the h81m-e has is a 2.0 but at x1 speed, which is terrible, so its deffinitley the right choice right? i mean getting the h81m would be pointless with the card im getting? but yeah, i understand about the minimal difference bweteen 3.0 and 2.0, was just making sure that a 2.0 x16 (or 3.0 x16) is better than the h81m's 2.0 x1

ahh ok, thats what i was wondring the most, i dont really care about the 1-2% drop in performance from a 3.0 to a 2.0 xD but thanks for helping me clear that up, tbh the website wher ei configured my pc buold should have stated the PCI slots that the motherboard had, would hav ebeen a distaster if i didnt decide to look it up as i would have ended up using a gtx 770 in a 2.0 x 1 ahaha, disaster avoided
