SLI or CF, took several days with doubts and with each passing day, there are people who tell me that SLI is better than CF, and others to mount a single card, but the problem for a card to play 1440p maybe come up a little short, play with my 6970 gw 2 on 40 fps and some time to time in slumps. Do you think?
As DarkSable said, you need to elaborate a bit and provide some more info.
If you are in a rush and on a tight budget the easiest fix will be to look for a used 6970 to crossfire with your current card (assuming you have a powerful enough PSU).
Regardless of whether you choose to go with SLI or CF, you will run into the same problems: heat, power consumption and occasional scaling issues.
When I switched to a 2560 x 1440 monitor i picked up a used 6950 to CF with the 6950 I had currently owned. Two 6950s generally handle any game at that resolution and this option only cost me an additional $150.The only game that really gives me any problem is Battlefield 3 in multiplayer, but that is because my CPU bottlenecks the cards.
However, I have also run into a few games that are not optimized CF or SLI. Blacklight Retribution, for example. And often when a new game comes out you will need to wait for a patch for improved performance. This is where a single card solution makes things easier.
If you can, I would wait a while for the 8000 series to come out in early 2013.
Also, it would be easier for people to make recommendations for you if you provide the specs of your PC and budget.
When new cards arrive, they will cost an arm and a leg simply because probably AMD will unveil before Nvidia again, and a HD 89** will cost extra due to no competition. Also there is the issue of new drivers being not mature enough. The OP needs a new card now. XFiring a second 6970, i don't recommend, considering the bad reputation of these cards in couples. Also it is a relatively high resolution, the OP is talking about. I'd recommend a 7970 Ghz Edition card with custom cooler. AFAIK HD 7970 Ghz is doing better than GTX 680 in higher resolutions. SLI/Xfire of GTX 670 or HD 7950 seems viable too.
No no no no no! Sorry, but this is the point of benchmarking, not just comparing paper numbers. Even poor benchmarking is better. Thank you for coming here at least.
Your computer has good specs and would have no problems with modern cards. Seeing how we can't predict the future, I'd start with a single 7970, it will play GW2 @ 2560x1440 on max with 40-50 fps so say Toms.
Make sure you have the 12.11 drivers (they actually make a differnce) and if you are comfortable overclock it (they have a good overclocking reputation). If you are still unsatisfied buy a second and use the Radeon Pro 3rd Party Utility
screw for any 8970/8950, they're even still doesnt exist right now..
in the future, if your card is not fast enough, sell your card, get another 500€ and buy the another fastest card available that day...
but if you have a lot patience, then you have to wait until the launch of 12870...
If you can wait a little bit longer, 999890 will thousand times better than any fastest card available today..
And good combination between this card and driver 978932.99 will blow your head, believe me..
That's even better if you can wait to buy your new graphics card 1 hour before the end of the world...
there is a lot of point in jumping the gun now or even in future to a 7900 series card coz older cards get cheaper dont they ? and 7000 seriea is not even old not atleast for a year.
a lot of people are still buying 6000 series cards even today coz they offer great value.
so saying jumping gun now is ignorance coz 8xxx series cards will suffer from immature drivers, high prices and.low availability at launch ..so you are wrong
Whoa, easy there mohit. I was trying to prevent OP from buying something he may not need (a new graphics card). It is not going to hurt anything to get the monitor first and then a new gpu a week later if need be. I really don't understand your point anyway.
