2 ati 7770 vs one gtx 970

[dontsh00tmesanta]

Being that the 7770 can be had for $70 or less should would it in crossfire perform vs say a 760

 

[lyssword]

970 is not 760. And I wouldn't recommend vs 760 anyways, due to 7770 only having 1gb ram, and less compute power. 2x 7700 * 1.6 = gtx 760

Never, ever, EVER prefer crossfire over equal or better performing single GPU setups. It's just not worth the hassle. Crossfire setups are more prone to software issues (incompatibility due to drivers or crossfire profiles), more likely to cause inconsistent framerates, suffer from worse frametimes...

Not only that, but dual 7770 is incredibly bad value for money if you're paying $70 each. That's $140 for a setup that can barely compete with a single R9 270 which you can get for as low as $110 after rebate: http://www.newegg.com/Product/Produc...-545-_-Product

It'd be good to know what CPU and PSU you have, just to make sure your graphics card choice makes sense

970 all the way

970. for a few years.

Also ordered a capstone that I was gonna use for my next rig but used this instead

And 8320

Unless you already have a 7770 and can get one used for very cheap. I don't think it would be worth it. If you are purchasing a card, I would not recommend SLI or Crossfire unless you are purchasing some of the top tier cards. Otherwise there is usually a better card that you can use that will have less bugs with launch titles etc.

Also the 7770 has low VRAM doesn't it? So you would be limited by that even with the two GPU cores running.

Did you mean to compare to a 970 or a 760? A 970 is no question but considering they are around 350 I am not sure it is what you meant, unless you currently have a 7770 and were looking for a cheap upgrade.

if you have one 7770 sell it and use the money towards another card. 280's have been hitting really low sale numbers in the USA.

its a bad idea to crossfire on low end cards. VRAM usage in modern games is hitting 3 - 4GB at 1080p. Sell the HD 7770 for 50 bucks. Get a R9 280 for USD 170.

Yea currently have one 7770 right now

Another question would be 8320 and gtx 970 which would bottleneck which? If at all

 

[DownTheSky]

8320 will slightly bottleneck 970. But should be ok for now imo.

 

[Deders]

I wouldn't call it a bottleneck, I expect GPU will reach 100% usage in most cases but it might not perform as well as an i5 or similar.

 

[raghu78]

The latest games like Farcry 4, AC Unity, COD AW, Dragon Age Inquisition are GPU limited even at 1080p. Overclock the 8320 CPU to 4.5 Ghz and it will not bottleneck especialy when you try to play at the highest possible settings.

 

[toyota]

um that 8320 will most certainly limit a 970 unless you are trying to crank every single setting and use full AA. most people use common sense to adjust a few settings for the desirable framerate which is usually staying above 60 fps. and the 8320 cant even maintain 60 fps in some games so I consider it a playable bottleneck in those if you want to use vsync. if you dont use vsync and dont mind minimums in the 40s and occasionally in the 30s then the cpu will be "fine".

 

[Deders]

Yeah I guess it depends on what is important to you.

 

[digitaldurandal]

Yea currently have one 7770 right now

There is a 280 for cheap in the hot deals section. You can sell your 7770 or keep it as a backup and pick that up. It won't be as strong as a 970 but it is less than half the price. If you can live without AA and ultra settings it will be much better than 2x7770s

 

[tweakboy]

Easy grab a 290 ... gl
