4870 Crossfire with 4850?

Ease · 28 Jan 2009 at 21:37

I have a PowerColor Radeon HD4850 512MB, and it's great and all, but Crossfire has always interested me. This summer its my 21st, and my girlfriend wants to get me something for ~£150.

Having just seen the "Sapphire ATI Radeon HD 4870 1024MB GDDR5 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail" for sale on OcUK, I was wondering if the two would work together in Crossfire well?

I've heard you can Crossfire any two ATI cards (that are Crossfire compatible) but all the example I see are 2 x 4850 or 2 x 4870, so would this mix up work? And would it work well?

<Edit> Just realised I put this in the wrong Board... but can't seem to delete it to move it. My bad!</edit>

If its your 21st in summer, surely you should wait till then for your present? 4850 prices will have likely dropped by then. I may get a second.

I dont think there is much point you getting a 4870 over a 4850, as it wont make the pair run any faster than a normal 2x4850 combination... unless you were thinking of selling the 4850 and buying another 1meg 4870 later.

I guess right at this moment its only £25-30 more than a 4850 with a decent cooler.

If a deal is only on for a week, and is going to save her a load of money, she won't care about getting it now and giving it to me then.

You cant crossfire any pair, they have to be from the same series, both those cards are 4800's though so you're alright there

Well its not, is it? Come this summer it will be cheaper still.

Edit: I've seen people claim to have crossfire'd 4870's and 4850's in the gfx card forum. Needs a post in there tbh (as you say above).

yes you can xfire them, and IMO go for it
