Can a motherboard bottleneck the video card?

[randir14]

I have this MB
http://www.asrock.com/mb/overview.asp?Model=K10N78

Like I said in an earlier thread I was looking to buy a GTX 570, but one person told me "the 8200 chipset will severely bottleneck that card".

Another person said as long as I have at least a Phenom II cpu (I do, Phenom II X4 955), the card will work fine since the MB has a PCI-E 2.0 X16 slot.

So who is right? I tried Googling to find examples of motherboards bottlenecking components, but I didn't come up with much information. I also watched this video that explains different ways a PC can be bottlenecked, but he doesn't mention motherboards http://www.youtube.com/watch?v=TGdo75gasaQ

Short answer is no. Running a 2.0 card in a plain x16 slot would though.

~Ha I just did a little research and found all of your other posts from various forums. Can you link to the TomsHardware post mentioning the bottleneck?

Thanks, I also asked on Overclock.net and HardOCP and people were saying it should be fine. I'm starting to think the first guy either didn't know what he was talking about or was fucking with me.

Nevermind I found the TH post. That guy seemed a little off especially with the useless image he posted. I suppose that technically he may be right but the bottleneck would be more like a negligible impact on the cards overall performance.

Video cards are the picky culprits most of the time. My new GTX470 did not want to play nice with a PCI 1.5 board, but my new PCI 2.0 board AM3 socket plays perfectly well with my AM2+ socket Phenom ii x4 940.

Your bottleneck will certainly be CPU based, but the motherboard itself won't be limiting to you. Still doesn't matter as almost all games are GPU-bound instead of CPU-bound anyway.

Just make sure you have the power supply for it.

Yeah I ordered a new power supply as well, I got this one

Now that is a hell of a power supply, nice choice.

I ended up buying a new case also, I got the Antec 900. Previously my idle CPU temperature was 50c, now it's only 32c. Holy shit...

Corshair products have slipped over time just like Asus. I would have gone with a Rosewill power supply.

Just an update, I ended up buying the Gigabyte superclock gtx 560 that came out today (yeah I know people say to not buy factory overclocked, but I never have much luck getting good overclocks on my own). From the benchmarks I've read it will match a stock gtx 570, and I'll save $100 bucks that I can use towards a Bulldozer cpu and am3+ motherboard sometime in the future.

That particular Corsair power supply is considered one of the best power supplies in the entire industry.

Rosewill is considered a second rate brand in all regards.

I use an Antec power supply myself, but that's mostly due to limited selection and the absolute need for one ASAP when i bought it.

Hmmm an AMD set up... Well I have not used AMD since A64 3000... The bulldozer had better be good. I mean intels sandy bridge is pretty great the now that the unlocked multi for overclock is not 1 damned thousand dollars. I still dont know why nvidia did the whole skip gtx 3 series shit.... Now lets see how that puppy can do with SLI...
