Can anyone help me decide between the following options please:

first of is 2 1.5gb cards better than 1 3gb?

so either 1 of these

or 2 of these

then are the nvidia cards worth the extra money? when I can get 2 of these for a lot cheaper.

Thanks for posting I will take a look at the 560 and 570s in that case. I will be going for a resoultion of 1920x1080 and im running an i7 920 overclocked to 4.1gb with gigabyte ud5 mobo and 6gb of ram Im also buying a Crucial M4 SSD with whichever gfx upgrade i go for

I have had a look and 2 560s is very reasonable how about 2 of these:

or 2 570s?

the GTX 580 is a much stronger card than the 6950, but is the 580 worth the extra money? It is up to you. A more interesting factor is the amount of Vram. As stated above, two 1.5gb cards will be much faster in general than a single 3gb card. However some games (BF3 being an example I believe) take great advantage of the extra video memory. On that basis I would be tempted to buy the single 3gb card now, and drop another one in there when the price drops after Nvidia release their new cards in the new year.
TI's

It is mainly bf3 that I am playing at the moment which is why I need to upgrade from my current 285. But I do play other games so want the best of eveything really.

Thanks for the help, those 560's look like a good buy and will certaintly out perform most but for some reason I am still drawn to the 580's. you say the 560's will run bf3 and all current games perfectly and the 580's is overkill for the price? The only main difference is the 580's are more future proofed?

edit: what is with the ti? if i found a 2gb 570 is 560 ti still better?

Thanks again for the advice, I am prepared to spend the money if its needed but that doesnt mean I want to waste money unecessarilly, so I think I will go for the 260s unless I can find the 270s on offer.
