Upgrading from 4890, CF?

[MikeHiow]

I don't think I am quite at the point where I need to yet, but it will be a consideration in the near future.

What is the best course of action? Would it be reasonable to expect a sizable performance gain by purchasing another 4890 and putting them in CF? Do I need to match cards by their variants?

If not, any recommendations?

Well I just upgraded from a 4890 to a 6970 at christmas. Part of me knows I shouldn't have and it was too early but thought 'sodd it'....

You are in the same position.

CF 4890 is bloody awesome performance-wise:

Not bad considering you can buy 2x brand new 4890s for like £180.

DX11 et cetera is nothing to take into consideration imo.

Tearing is another thing which you might suffer from with CF.

If you can find one for like £80 or so - I'd do it and wait for proper next gen cards or when the game engines improve for the eye candy to be too good to miss. Or when we are all gaming in 3d for example....

4890CF is a top performer imo....

Thanks - what sort out power consumption are a pair of 4890s likely to be pulling? I assume my Corsair 500W unit will no longer be up to the task?

Having looked at that yes you will need more power.

The 4890 is actually considered to pull 30W more power than the 4870 but that may be at idle.

This benchmark is as high as it will realistically go.

So if the 4870 CF is pulling 460w whilst on Crysis then I would suggest getting a 750w PSU which should be fine.

That might do it depending on the rest of your system. Read up on it tbh...personally on a PSU I'd always spend the money and get way over what I need bcos it's the one thing not to skimp on.

Hello.

I am very interested in doing the same. I currently have XFX Radeon 4890 (Part code HD-489x-ZSFR).

Im new to CF, so I would just like to know...

Do i need the same card with the same Part code? http://xfxforce.com/en-gb/products/graphiccards/hd 4000series/4890.aspx#2
Or will CF work fine as long as its the same card, with the same tecnical specs (GPU Clock ect)

Cheers

You can use any 4 series. with msi afterburnner theres a option to set cards to run same clocks or different. so doesn't matter if 1's a pre clocked

Things change a little if say use 4890 with 4350. cf then would double the mem to 1gig and not 2gig as the 4350 has 512 of mem

Thanks for the help
