Struggling to decide on GFX card(s) to power my new build.. help pls!

After some helpful advice from this forum I've settled on my new build except for what GFX card(s) to power it.

Because I've decided to go with a 27" Dell monitor outputting 2560x1440 - I want to make sure I have enough oomph to play the latest games at native res.

SO can anyone here help me decide? I'm looking for good solid performance but don't to go too crazy on price.

Currently I'm thinking:

2x 6870s in crossfire ($520 AUD) -- this very website recommends it as great bang for buck
1x GTX580 ($620 AUD) -- pros in that I don't have to SLI, but expensive and from what Ive read, not as good performance as the 2x 6870s
1x 6970 ($439) AUD -- to save money... could I get away with this and still run games at 2560x1440??

Should I go the crossfire route? Or shell out for a better single card?

Cheers guys.

The system:
MB: Asus P8P67 PRO
CPU: INTEL i7 2600K
RAM: Corsair Dominator 8GB (2x XMS3 4GB) PC3-12800 (1600MHz)

CPU cooler: CoolerMaster Hyper 212 Plus
SSD: A-Data S599 128GB
HDD: WD Caviar Black 2TB 7200rpm
OS: Win 7 Home Premium 64bit... 100 MSY
Monitor: Dell Ultrasharp U2711

More about struggling decide card power build
  1. The crossfire route is appealing but single more powerful card would be my choice. In here there are few games most cards in question at high resolution maybe it will help you decide
  2. Look into waiting for the 6950 1gb it should be cheaper and prove to be just as good as the 6950 2gb. In CF they should be pretty much the same perf as the 6950 2gb in CF. So maybe wait for those cards to come out.
  3. There is a benefit from the 2GB currently on the HD69xx cards at OP's high resolution.
  4. Well I mean in CF would the cards combined VRAM make up for it? Plus if it is (in the US) $270-$280 then he'd be able to get ermmm 2 for 540$ which would be pretty sweet if you ask me.
  5. They would still count as 1GB in crossfire and therefore loose to 2 x 2GB cards in benchmarks at that high a resolution. It was brought up here in the review of the HD69xx cards how they catch up at high resolutions,2818-9.html
  6. Ahhh, I see. I've been schooled in crossfire. Thank you rolli and mayan.

    I did see that in the article but I was just scanning. I thought it meant that it wouldn't serve as a problem XD
  7. Appreciate the replies... still no closer to deciding whether to take the Xfire route or go with a 580 as a single card solution??

    From what I've read so far, it seems I'll need to go crossfire if I wish to get decent FPS on many of the latest games running at max res?

    Hmmm... very difficult indeed.
