ok time to order some harware, thinking of going for ati this time (but still open NV if it best)
so what will i need to run my 30"
1*4870 or 2*4870
or a gtx280
 
DONT get anything with 512MB, and dont listen to anyone else that says otherwise. It's not enough for that res, i learned the hard way by getting a GX2, that has 512MB usable VRAM. Total slideshow with most games with AA.

Wait for 1GB 4870 or get a 280.

Read this before buying! took me ages to do all that for people in your position.

But it's also thought ATi do a lot better with less memory than nVidia (who might have gotten a little lazy since the 768mb GTX was released). Read all the reviews & see what you think

I dont know who stated that rumour, I stand by what I said before (someone else agreed).

512MB not matter how more efficient one is over the others Tech ain't going to cut it at 2560's nevermind 1920's with Full AA+AF+ Full other settings IMO.

Best look at 1024MB per card for that.

One Vendors Tech might get more mileage out of 512MB than another Vendors Tech but at the end of the day 512MB is 512MB and it will run out of steam and I would not even think of 2560x1600 with AA+AF.

I would want 1GB for that Res.

Also in Crossfire Jedi hinted at the card may add up the 2x512 to give you 1GB, any actual proof on this before peeps buy 2x512MB cards instead of 2x1GB card.

I personally would not use a 512MB card today (if your actually buying today) at 1920's with AA+AF and even if some games run ok with it even more so on the new ATI Tech it may not soon with newer games to arrive.

30" here & yes 512mb really not upto it in some games & it will only get worse so 1GB version & 2 x 4870 1GB each is a minimum or wait for the 4780X2

I only know that it's a pretty good bet that the 4870x2 will be able to share a total of 1GB instead of each chip having 512MB each (thereby hampering massive res' and AA/AF).

It's a good idea to wait if possible as it'll be a monster card if so. nVidia better start praying :D

Ahhh Karma, don't ya just love it ;)

Well we need see if it actually happens and still for now peeps buying 2x ATI cards to Crossfire same as buying 2x Nvidia cards to SLI will only get 512MB from both cards total of 1GB (if its 2x512MB cards your linking).

Nvidia would probs bring out a GTX280x2 however it would err cost a lot

How would it? it's faster, but is still 512MB. The GTX 280 has a 512-Bit bus anyway, so actually has more bandwidth aswell, even though it uses GDDR3.

According to this CF 4870's do beat 1 280

You dont understand. Read my fat long post i linked and get educated, seriously. I did it for people like you aswell. I'm not having a go, i really think you should read it. - Here.

When you run out of 512MB you hit a MASSIVE performance decrease, and things become a slideshow, as the VRAM starts swapping between system memory. You even sometimes hit single digit FPS.

512MB is not enough for 2560x1600 and no matter what ATI do, what drivers are used, or what memory tech used, it's always going to be a problem at this res, (and get worser as new games start using higher res textures). They could have GDDR 10 and a 1024-Bit memory bus but your'd still have this exact same problem of 512MB not being enough.

nVidia are stuck between a rock and a hard place. Their volume-sales are also in the toilet compared to ATi (so I gather from the Web) :D

OT: Will anyone ever stop calling them ATi instead of AMD? I sure won't :cool:

ATi is still the brand name so it's still ATi in my mind.

It does not matter that in some games its ok with little AA applied.
U should make sure you have enough mem for any game that your likely to be playing over the cards expected useful life as it should be the GPU power that is not up to the job & not the MEM.

GRID is the first game to show me that 512MB on an ATI card is not enough at 2560x1200 & even on the 4800 line the fps are not impressive in that game.

I know you are talking from, your, experience and I'll admit I'm also waiting for the 1GB cards and the X2 before taking the plunge this time around, but have you read any of the reviews linked in the other thread?
