A couple of questions

[hobib_ali]

Hi

Firstly in my current pc i have ATI 12.8 drivers with an ATI card, so if I install a nvdia 680 would I have to uninstall all ATI drivers?

I mean take every thing ATI related off my PC? then install the Nvdia drivers, or do i just leave the ATI stuff including the application profiles and just install nvidia drivers?

Reason being is many people state that they have ati and nvdia on 1 machine, so mix drivers wont be an issue?

________________________________________________

2ndly can you mix 2 680s or 2 7970s of different brands on one machine? example 1 could be sapphire and he other HIS, also if 1 was refrence and the other non refrence, can you sli or xfire?

Im thinking that the diffrent clock speeds of to diffrent 680s/7970s will cause issues?

Thank you, just some information I need clarification on from the knowledgable forum members.

Yes.

Everything.

They run hybrid machines, i.e. machines with a main AMD card(s) and then a lower spec nVidia card for PhysX only. Having two sets of drivers on your machine shouldn't cause problems but is has done for a fair few people previously .

2ndly can you mix 2 680s or 2 7970s of different brands on one machine? example 1 could be sapphire and he other HIS, also if 1 was refrence and the other non refrence, can you sli or xfire?

Yes you can mix different brands of the same cards.

Im thinking that the diffrent clock speeds of to diffrent 680s/7970s will cause issues?

Won't cause an issue on paper although I personally believe you should set the clock speeds to the lowest common denominator. So if one card clocks to 1150 and the other to 1175, I would set them both to 1150.

I believe differing clock speeds have the potential to introduce microstutter or make it more noticeable than with identical clock speeds. This is just a loose theory though and I know others who run different speeds with no concerns.

I ran 2 different 680's on different clock speeds without issue. I only changed to 2 of the same brands because of going water cooled.

Use driver sweep to get rid of AMD drivers if you are switching

If you're considering 2x 7970s, take a look at 2x 7950s. The performance is so close with a bit of moderate overclocking that you'll never notice the difference, for a chunk less money.

7970s, GTX670s and GTX680s are all over priced for the performance they give.

yes there is a massive price difference between the 680s and 670s and same again with the 7950s 7970s,

but considering the 670 thats the same price as a 7970 but many people would prefer a 7970 over the 670, yes?


yesterday I bought the msi lightning for £360 and free delivery, this included the £20 discount, but somthing on the back of my head decided that I should have gone for the 670, but after reading a few reviews it shows that the 7970 is more comfortable with my default resolution 2560x1440 while the 670 is more of a 1900x1080 resolution...

Apparently the 670 struggles playing Arkham Asylum on 2560x1440

I wish I could wait a few more months for the 8000 series cards or the nvidia 760/780 as my 5970 xfire really struggles with todays games on high resolution/settings and the buzzing/rattling fan on my 5970 is driving me up the wall.

You should have gone for a 7950 and overclocked it.

Cards above 7950s are just not worth the price, they're a waste of money.

Unless you have the money and are willing to part with the extra for 5-10% boost in performance. I know i did, and was.

Without knowing their finances, how can you say its a waste of money when value for money is in itself subjective?

Because it's not subjective. Whether the "value" matters or not is what's subjective.

With a moderately overclocked 7950 you won't notice the difference between a 7950 and a 7970 at the same clock speeds. It's less than 5% for more than 30% more money.

Agreed.

in your opinion

personally, based on the user results I've seen on here of less than optimal OC's and the resulting minimum frame rates, for me personally a 670 / 7970 would be the lowest step down I would go to

You are putting your opinion as Gospel again I see. Far to many 7970/680 owners will disagree with you.

Why buy a skoda if you can afford a Ferrari?

It disturbs me that you feel the need to tell me that my own opinion is in fact, my own opinion.
