    Do not forget the power usage, the GTX has a advantage here to.

    Yep, there's a lot we haven't covered here due to the situation explained on the first page, which is why we haven't given it a score or made any sweeping conclusions about the product yet. :)

    £300 estimated? Are they having a laugh?

    I would have thought £250 would be a better price given the direct comparison to two HD4850's (ie two would cost roughly £250).

    Performance does look good though (as long as the drivers cooperate)

    It's got 2x1GB of memory, not 2x512MB... 4850 1GB cards are about £150 inc. VAT (edit one here for £147: http://www.dabs.com/productview.asp...electedId=11137&NavigationKey=11137&InMerch=1), which means it's not actually too bad. Look at the Far Cry 2 numbers (4870 1GB vs 512MB) to see why you need more than 512MB of graphics memory moving forwards. :)

    About Nvidia SLI with multiple displays.

    You can actually only drive displays connected to the primary GPU. So with the 9800gx2 you have to use the DVI + HDMI. For a Dual video card set up, you can only utilise the Two ports on the primary card.

    Tried it myself on my 9800gx2.

    Good to know, thanks. I haven't tested the rel 180 drivers on the GX2, but with SLI disabled, you can connect three monitors and all three work. At least... that was possible at launch. :)

    I got my Gigabyte 4850 with a 700MHz pre-overclocked core from Scan for £131 but unfortunately they are now out of stock and the price has gone up too :grr:

    http://www.scan.co.uk/Product.aspx?WebProductId=874142&Product=1GB+Gigabyte+HD4850,+PCI-E+2.0(x16),+1920MHz+GDDR3,+GPU+700MHz,+800+Cores,++S-Video/+DL+DVI-I,+HDCP

    But when comparing to an X2 you also need to consider that you don't have to invest all in one go if you choose 2x 4850 over a single X2.

    Prices are increasing because of the exchange rate changes and weak pound. :)

    I probably would too but it's not responsible for us to make a sweeping statement like that about a product before we've tested it properly. If the 4850 X2 can get close to the 4870 X2 in more of the new games we're currently testing, then it could be a good option IMO. :)

    Aye, I picked up the same Gigabyte 4850 from Scan not long ago for £131. I was amazed how cheap it was.

    Actually, I just ordered a 4870X2 from Amazon for £301, but it's not currently in stock. At that price, I thought, "Well, if I spot one somewhere else in the meantime for less, I can always cancel..." but the chance of anywhere else being cheaper is slim. It'll about 6-8 weeks for stock (so an e-mail they sent me said) but to be honest, I'm quite busy right now so can wait without issue. Thinking of cancelling it and ordering a Canon 40D body only, right now. I'd probably get more out of a 40D overall.

    I have 2 HD4850's and 4 monitors under windows xp. The last time I enabled crossfire and tried using 4 monitors it didn't work. Only the 2 screens attached to the primary card were enabled. Has this changed recently? Can I use all 4 monitors with crossfire enabled?

    It's interesting how the 1GB 4870 has double the performance of the 512MB 4870 in FarCry 2, but we don't see this in Crysis. I would think that Crysis would thrash the memory more so than FarCry 2.

    yeah, we were bumping right into memory bottlenecks with AA enabled. :)

    interesting to see the 4870X2 minimum framerate increase from 31 to 39 when 2xAA was applied in the Crysis 1920x1200 benchmarks :eyebrow: :confused:

    Crap, that's a typo - my apologies. It should now read the correct value, 29 fps.

    It seems like ATI is pricing this based on the performance, not just on what it actually is.. 300 pounds is about $475, which is more than the price of THREE 4850 cards. Doesn't make much sense to me, unless if people are completely scared of Crossfire.

    I hope they don't spend too much money in R&D for cards like this that doesn't push any limits.

    And they say only noobs look at gpu-ram when they buy a new gfx-card... heck i have bought cards with too little ram twice!! First time was the 8800gts 320, praised to the skies, sucked like hell and no games actually played well in 1680x1050. Then i bought a HD4870 512mb, praised to the skies yet again. "512mb ram?? the competition has 800+ " I say to myself. But the fool that I am went out and bought one. Well here I am looking for a new buy 2 months after the last one... yay!

    512mb ram gfx card = 19" monitor
    1GB gfx= 22" monitor.

    wrong, you are comparing uk and us pricing, 300£ is the price of two 4850's, in the us the 4850x2 would not cost 475$ but far less.

    A 4850x2? there have been rumors about such cards for a long time, it would kinda make sense as the gap between 4870 and 4870x2 is pretty big, but I doubt any 4850x2 cards will ever actually make it to retail, it's just too late now and the next gen of cards too close.
