Computer freezing while listen to music with HDMI.

Guys, thanks for the hints and answers.
I have a question.
My motherboard doesn't have any PCI Express 3.0. Only 2.0
Both R7 260x that I tested was PCIE 3.0. I didn't noticed that my motherboard didn't got PCIE 3.0. The weird part is that I got video normally even that both graphic cards were 3.0.
Does PCIE 3.0 works on PCIE 2.0 slots? What this means after all? I thought it was like the DDR versions of a RAM Memory. DDR1, DDR2, DDR3 for example.
But as I said before, both gave me trouble.
The one from XFX do random freezes and video crashes and even a BSOD on YouTube. The one from ASUS gave me thoses random system freezes.
The last freeze that I got I wasn't using the audio from hdmi, but I was using the hdmi video, and, after a few hours, BOOM, the whole pc got frozen.

So... PCIE 3.0 graphic cards should work on a PCIE 2.0 16x?

 

i remember, once i tried to install the realtech amd hdmi driver, my pc crashed even worse. So I don't touch it.

some people recommend to manually downgrade via bios from PCI 3.0 to 2.0 when they have problems like yours. The bandwidth is mostly sufficient. But other people should answer this.

 

Been seeing this myself with the later drivers. Earlier drivers are fine though.

 

Yeah.
Well, I did some searches on google and I found the answer. It works. A card with PCIE 3.0 works fine on PCIE 2.0 slots.
I'm more relaxed now that I know that I didn't screwed with my graphic card.
I hope the store give me some credits on their website, so I can buy a GeForce GTX 750 TI 2GB from the manufacturer Zotac instead of a new R7 260x.
Is this the NVIDIA answer to the R7 260x? Because I want a card that have the same performance as a R7 260x was supposed to have.

 

The 750ti is a faster card than the R7 260x, and it will be faster with the CPU you have.

 

I see.
Thank you.

 

yes the GTX750Ti is faster and more power efficient than the r7 260x cards

 

Thank you.

 

Hey, guys. How are you?
What do you think of this card?

What's your price limit? Are you in the US?

 

I'm from brazil.
I think $400 is my limit.

 

400R$ or USD? Are you buying in Brazil?

 

I meant USD to make it easy for you. On R$ I think about buying a card around R$ 800.
