worth waiting for 4870 1GB?

As long as you don't use any AA.
look at 4870 CF 512MB cards=512MB per gpu now look at the 4870X2 that has 1GB per gpu

That looks like a crossfire driver issue as 1 4870 is faster than the crossfire setup. The 4870 on its own is also faster than the gtx280 so it can't be the memory.
Faulty results a single 4870 scores 43.9 at that res but xfire 4870 drops to 30.4fps?
Has to be a crossfire/driver issue and not memory or the 4870 would be hit by the same penalty whih it isn't
Aye, I agree. One 4870 faster than crossfired up 4870s?. Doesn't compute. Also look at the single 4870 with it's limitation due to the memory trailing the GTX 280 monster
. Oh wait, it isn't 
.Hopefully this Crossfire problem will be sorted out soon, as one card can't be faster than two. We might not see the X2 4870 FPS with a single 4870 though due to the memory limitation but it will be faster than a single 4870 at least at that resolution.

misiowec>I would like to respectfully disagree. The 4870 512mb is no match for a 280 at 2560x1600 playing Grid with AA applied.
The 280 has a faster minimum framerate and gaming on a 30 incher min framerate is everything. Also it lacks the smoothness of the 280 as every so often the game freezes for a split second not like long but certainly noticeable.
The 1gb card won't give it tri sli or quad crossfire peformance but it will certainly help the 4870 at 2560x1600 with AA applied.
In theory it should put it on a very even level against the 280. In my ownership of both cards *** one thing that sticks out besides the heat and power consumption is the 280 more or less at least in the games I play 8 times out of ten has the higher min frame rate.
Last time I play Grid with the 4870 using previous drivers the min frame rate was 13-14. The 280 was about 30 give or take. I hoping for good things to come out of the 1gb version.

I have noticed a few driver issues in reviews of 4870 CF - and seeing as a new driver set is just coming out, Im hoping its going to be fixed before I invest a huge amount in my new setup
Not going to go with nv, it just isnt worth it imo - plus Im looking to get hdmi audio out of the video card also

Sorry if I suggested that the 512Mb 4870 is better than a 1Gb 280GTX, someplace, as that is not the case. Obviously we need a 1Gb 4870 to be able to compare the cards on an equal basis at high resolutions (possibly with AA / AF too), though I suspect the 280GTX will pull ahead even then.
The fact that you get half the framrate with your 512Mb 4870 just shows it's (mainly) a memory issue at the moment. I'll see what sort of framerates we can get when the 1Gb 4870 launches, but will ultimately decide on price.
Agreed, the 280GTX is still too expensive. Besides I'm not bothered about having the best, all want is for games to run at the native resolution of my 24" with AA and AF (Crysis being the exception, I just want native resolution there). Once we have 3 or 4 competing 1Gb 4870s the price should be no more than £200. I see myself buying in a months time.
Exactly how I plan to use it
And a Q6600 at 3.2 - 3.6GHz should have the grunt. Sure a E8500 will clock higher, but I'm not after the very very best.

Well it be interesting to see what the 1gb has to offer. I think with the 1gb version it should be close and possibly even matching and maybe in some games surpassing it.
The 4870 has every bit the potential to best the gtx 280 as when you look at a gtx 280 while it seems to be a big performance boost from the 8800gtx card it is a squandered opportunity. It no really better than a 8800 gtx sli setup overclocked as that was faster.
What is currently keeping the 280 afloat is at the moment it's very good performance on min frame rate at extreme res. Now if ATI can capatialise with *** 1gb offering and including some tweaks over the standard 512mb version then for gamers the choice is welcome. I always wondered why most 30 inch setups are predominantly nvidia based.
It would also force nvidia into some quick action if the 1gb ATI version is every bit as good as it 512mb sibling. Will Nvidia release the apparent 55nm version. Or will they do what they did last time with the 8800gtx cards (3 days before the x2900 release) and release a driver which improves performance to a new level.

I'd like to see actual VRAM use for the 4870 at 19x12 with AA, from what I've heard some games do you more than the 512MB but I've not seen any complaints with pauses due to paging.

You can pre-order an Asus 1GB version for only a few quid more than a standard 4850 512Mb, tempted to just pay the tiny bit extra and be on the safe side. Nothing to lose really.
Little point with the 4850 given the combination of DDR3 VRAM and a 256bit bus. The 4870 should use the memory much more efficiently with it's DDR5 VRAM. If it's only a little extra though you've got nothing to loose, agreed. The additional memory for the 4870 is much more expenisive, but then DDR5 is supposedly in short supply.

Reading a few reviews comparing a 4850 and a 4870 at the same core clock the DDR5 doesn't actually make a lot of difference, so I'm not sure how much you'd gain even on the 4870.
