PCie slots and GPUs

JhonConners · May 30, 2016

I have a mother board that supports
"1 x PCI (3.3V/5V)
1 x PCIe 2.0 x16
1 x PCIe x1" According to http://www.cpu-upgrade.com/mb-MSI/760GM-P34_(FX).html

Does that mean I have to find a gpu that goes into a 2.0 x16? I was looking at a r9 380 but want to make sure it'll be good to go before ordering it.

PCIE 2.0 and PCIE 3.0 are 100% compatible, yes it has less bandwidth, but it would take something like a 1080 to expose even the slightest differences. A r9380 will say PCIE 3.0, but it will fit in and work in a PCIE 1.0 2.0 or 3.0 slot.

Robert Cook :

I understand it will fit, but in a LinusTechTips video he mentioned that a PCie 1.0 x16 was equal to a PCie 2.0 8x and so on.
So was just wondering if it'd be fine

Robert Cook · May 30, 2016

yeah it will be just fine. PCIE 3.0 X8 is plenty for just about every card out there. we have an article on that somewhere here.

Robert Cook :

Well yes, but this card is a 3.0 x16 slot where as my Mobo only has a 2.0 x16

Robert Cook · May 30, 2016

yes, but that is not an issue, the fact that the card says PCIE3.0 is just a statement that it supports the full bandwidth of PCIE 3.0. But, a card like that will never move enough data to warrant needing more thna PCIE 2.0 X16 or 3.0 X8. Did that make more sense? please tell me If I am making no sense.

Robert Cook :

Yes that made a lot more sense. Thank you. So as long as my Ram and CPU won't bottleneck (and besides heat and wattage) there is nothing to worry about in upgrading this card?

Robert Cook · May 31, 2016

yes. what is your Processor? and how much RAM?

JhonConners · May 31, 2016

Robert Cook :

AMD FX 4300 Quad core 3.8Gz
8GB ADATA RAM Not sure speeds

well you might want to overclock that processor slightly(if you can), it could cost you a few FPS in some games. other than that the system looks fine.

Robert Cook :

What would you recommend?
I bought and installed a hyper 212 evo last month so I should be fine.

Robert Cook · May 31, 2016

what is your motherboard? that cooelr is fine to get you over 4.0 GHz, but the motherboard determines if you even should overclock.

It's the link in the top comment, but here ya go

JhonConners :

so true, sorry about that.

It seems that motherboard is not really going to handle an overclock, the board looks too anemic. I am afraid you will just have to deal with some lost FPS in more CPU demanding games. perhaps Zen will be an affordable upgrade in October.

No dude you're fine

What do you mean by Zen?

Robert Cook · May 31, 2016

that is supposed to be AMDs make or break. it is so far shaping up to be as good as haswell (so like a 4790K) if not better, but it is hard to know as there is no proof. it is supposed to undercut as well based on some sources, which would mean cheap CPU power for all.
