Which (GPU) way to go with 2560x1440?

post #1 of 21
Thread Starter 
Ok, so I am wondering the following:

I currently have a 7850 CF setup and im about to buy a 2560x1440 screen.
Because the 7850 is 'only' 2 GB im affraid that isnt gonna hold for long when the new games are coming out..

My fps with this setup is quite nice and in benchmarks and games im well ahead of a single 7970 or gtx680.
Still im thinking about the future and I think its better to go for a 3gb GPU now..
I know a single 7970 wont give me high fps on max settings, but it is well known that the 2560x1440 dont demand high settings because of the compressed pixels.

- Is it wise to sell the 7850's and buy a 7970, so i can CF that one in the future and have 3GB instead of 2GB?
- Can i also go for a 7950 and overclock it so i get 7970 performance and still have the 3GB benefit?
- Should i stay with my 7850's and hope 2GB is going to be enough for like 2 years...?
- Or should i wait on the ATI 8xxx series?

Thnx in advance!


Ps the 7850's will sell at 300 euro's and thats exactly the price of a second hand 7970 (7950 is around 230 Euro)

For 2560x1440 you need a 7950 or a 7970 if you want to max out your games

my 7970 cannot max out most current games and get a steady 60 fraps...

I'd say keep the 7850s for now because my old 460s in sli ran very well at 1440p with only 1gb of vram. Plus you wont really need AA with 1440p, and youll do better with power processing horsepower rather then the ram.

A 680 does just fine with only 2gb because its got a lot of power in it, your two cards should last at least two more years, swapping to a 7950 or even 7970 would be a downgrade or small side grade if you are gonna benefit from a single 7970.

however I hear the support for 2 cards isn't great right now on AMDs part so that would be my only doubt. Maybe sell them and get a 8970 at release and that would be a better upgrade then a current 7970

2gb vram should be find so choose whichever card suits. You would be maxing games out with a single 680 OR 7970. I use 2 7970's and can max pretty much everything at this resolution with AA.

how is your experience with CF ? generally single GPUs provide the best and most consistent experience. a HD 7950 overclocked to 1.1 - 1.15 Ghz matches HD 7970 Ghz and will help you play most games at very high settings at 2560 x 1440 . you might have to turn down MSAA to 2x or turn it off in a few games. the price perf of HD 7950 is excellent. alternatively waiting for the HD 8970 / HD 8950 is also a good option.

I actually think you might be ok with the 2GB....

I have 2 670's in SLI and play at 1600p...They handle it like a champ. The reason is because I can run with very little AA since it is already at such a high res...

With you playing at 1440, you could turn down the AA a little to make up for the increased screen res, hence reducing the load on the VRAM and it will look just as good...
