Graphics Slot

[anjivarmapvs]

Hello,
I own Gigabite GA880GM USB3 Rev 3.1 motherboard with Phenom II x2 555black edition cpu. I wish to instal a graphic card and doubtful to which GC to go? Sapphire radeon HD 7750 or Sapphire radeon HD 7770? which would be better? Or.... you want to suggest some other Graphic Card?

 

[helper800]

7770 is the way to go in your situation =D

Please tell your whole specs,your powersupply and budget

 

[devilofdeaths]

i would say a 650Ti would be the best option but the 7770 is a good card to

Hello,
I wonder whether, the motherboard with PCI E 2.0 x16 interface ( GA 880GM USB 3 Rev3.1) supports a graphics card like supphire HD 7770 with PCI E 3.0

Hai guys!
I wonder whether, a motherboard (GA 880GM USB 3 Rev3.1) with PCI E 2.0 x16 interface can support a graphic card like sapphire radeon HD 7750 or 7770 with PCI E 3.0 version?

 

[ASHISH65]

Yes it will support 100%.pci slot are of same size and are backward compaitable.so you put pci 3.0 gpu in pci 3.0,2.0 and 1.0 slot without any performance loss.

 

[djangoringo]

Yes, that board supports any pcie 3.0 card, either the 7770 or 7750.
PCIE 3.0 is backwards compatible with previous pcie, since you have 2.0 at 16x there's no restrain from both cards.
Make sure you have a decent psu with 300-450W.

 

[ASHISH65]

I already answered to your previous thread.do not create extra.

you put pci 3.0 gpu in pci 3.0,2.0 and 1.0 slot without any performance loss.

That is dead wrong. You can put a PCIe 3.0 card in a 2.0 slot without a performance hit FOR NOW, because there's no card yet that's faster than a PCIe 2.0 x16 lane. (3.0 is getting utilized for crossfire and SLI setups), but any modern card put on a PCIe 1.0 slot is going to be slow as all heck. You also have to be careful, because not everything is 100% compatible with PCIe 1.0.

OP, you're fine, however.

1.0 slot comes with latest chipset . you are wrong . if chipset and processor are capable of handling that gpu no bottleneck . 3.0 to 2.0 is correct because amd mobos now not move to 3.0 . gpus are work in all slots but performance is lower in 1.0 . but 2.0 to 3.0 no performance issue .

Test in u r system . put that gpu in pci 2.0 x4 slot compare pci x16 result with x4 result .u see performance loss clearly . because 2.0 x16 slot utilities 100% gpu performance (7950) . but x8 20 ~ 25% loss . in x4 25~50% loss. but all are 2.0 . So use x16slot .

there will be no measurable FPS difference @ x16: See even high end gpu loses 3-5 % performance

only there is performance loss when crossfired or sli

99% of pci 1.0 mobo supports pci exp 3.0 gpu.only there is problem with very old mobo.Intel mobo after 945 to g41 have no problem due to bios update.

Make sure that for hd 7770 you have good 400w psu.

Thank you very much. I run with SESONIC 530 Watt psu. So i should't have any problems. Thanks once again.

 

[djangoringo]

No, it's a quality psu, the wattage/amps of it, is suffice for both cards, or ever better cards.

Thankyou. So should i go with Sapphire Radeon HD 7770 and crossfire it with on board graphics AMD/ATI Radeon HD 4250?

 

[djangoringo]

You can't crossfire the 7770 with the onboard graphics.
It will operate as a single card, it's a decent card, it can play any game at low/mid settings @ 1080p.

Oh..... You mean to say i cannot crossfire the Graphic card 7770 though i have crossfire enabling in my motherboard. Or was it, that on board graphics is only Radeon 4250 and discreate is much higher (7770)??

 

[djangoringo]

1 x PCI Express x16 slot, running at x16 (PCIEX16)
(All PCI Express slots conform to PCI Express 2.0 standard.)
1 x PCI Express x1 slot
2 x PCI slots

Nope, no crossfire possible, that hybrid crossfire function is worthless.
