 ;D Thought I would share this one to show there is still bargains out there. I am presently running two ATI 4870`s in crossfire. @4.1GHz (stock 2.67GHz)
I purchased two brand new cards from reliable sellers on E-bay.
Friday--- XFX HD 4890 1GB 850MHz  for £87
Saturday---HIS 4890 ATI Radeon Turbo Graphic Card 1GB 900MHz 4Gbps for £107

Both still in the box,crossfire-x enabled DDR5,plenty of room to install both. fans may be a bit louder. Will be here mon/tue.
Will I notice much difference.???
tks

I'm not too familiar with the ATI/AMD line of cards but I wouldn't expect much of an improvement, especially since the 5 series of cards is out now. The thing about crossfire/SLI is that usually a single latest card is better than two of the best older generation in duo.

Anyway, the Radeon HD 4890 CrossFire has proved to be a worthy opponent to the GeForce GTX 285 SLI configuration. The latter is generally faster at low resolutions, but ATI’s configuration secures a draw at 1920x1200 and higher resolutions. Therefore, we can expect it to be faster than the GeForce GTX 285 SLI tandem from the same price category. We will check this out practically in an upcoming review.

As for practical recommendations for gamers, it would not be wise for us to make them basing on our list of 15 games only, especially as you should take into account the display resolution you are going to play at. Still, we can note that if you want maximum performance in Crysis Warhead or Far Cry 2, you should consider building a GeForce GTX 285 SLI, but a Radeon HD 4890 CrossFireX configuration would be better for F.E.A.R. 2: Project Origin or Tom Clancy’s H.A.W.X.

On par with GTX285 and even touching the 295 on some points.(http://www.hardwarezone.com/articles/view.php?cid=3&id=2903&pg=1) Considering the price of these single cards you will nearly always come out ahead with two cheaper cards in SLI/Crossfire.Remember the GTX285 was running in Sli for these tests, .Also tests were run with HD4890 at stock 850MHz, They will be comfortable at 950MHz
Will keep you posted.

Kind of irrelevent, the 285 and 295 are very old and are about the same generation as the 4xxx ati series so whats your point? Of course crossfire 4890's are going to be faster than a single 295, as a 295 is only 260's in SLI. Of course the 4890 is going to be up to par with 285's in SLI.

I'm saying a really good single 5xxx series ATI is probably better than two 4xxx series in crossfire. The argument with nvidia is erroneous because they have not release a 5xxx contender yet. This has been the longest gap nvidia has ever had in a long time without a new release of a card, the new nvidia cards are coming out this spring though, they would be up to par with the 5xxx series and probably a little faster.

One of the "best" nvidia setups RIGHT NOW is dual 285's (lets forget about triple SLI for the moment), but I gurantee the new nvidia card will be faster than dual 285's, and dual 285's will be cheaper than the new nvidia card. That's always how it is. Dual of the older gen is always cheaper but still slower than a single of the newer generation.

If you check out the tests on this link you will see that even my present rig  2xHD4870 can easily match the HD5850. The HD5850 was highly overclocked,whereas the hd4870 was only running at 750MHz. Both my cards run at 780/790 core and 1080/1100. , THE 2 HD4890 are 1GB and will run 950MHz. So when you look at the price of one single high end card(even the HD5870) and my purchase of 2 cards at £197 there will not be an advantage. My present rig is achieving 23,000+ cpu marks in Vantage.
