Gtx 260 sli vs 5770 crossfire

[ebkboy]

is it worth going from the 260s to the 5770. i have read that the 5770 in crossfire are amazing.

5770 == 4870 == 260

so you would just be moving sideways
you would need to go to 2 x 5850/5870 to see a noticeable benefit, and only at 2560x1600

4870>>HD5770/GTX260.... Anyway. HD 5850 is the smartest deal in my opinion...

again we have to say this on the forum, those benchmarks are from the beta driver release of the 5770, and even if the 4870 is better by a small margin (still), don't use ">>" that implies much greater

Excluding DX11 from the equation, it would indeed be mostly a sideways upgrade from sli 260s.

... and since DX11 isn't really necessary for another year or so, that also makes it an untimely upgrade and a waste of money.

I think we've solved the question: Might as well just keep the 260s until DX11 starts to obsolete them.

 

[mindless728]

oh so you already got the 260s?? LOL DUDE. WHY bother changing. DX11 aint necessary. And GTX 260 SLi is equal to GTX 295!!

wow, way to not read what the OP said

though really, stick with the 2 x GTX260's, unless you have the cash for like $600+ in GPU(s)

@ Ebkboy: As the others have said: Stick with your dual GTX260s'.
In point of fact, most benchmarks show the HD5770 as being slightly slower than the previous generation cards in its performance range (HD4870/GTX260) so you'll most likely see a performance drop off along with the loss of PhysX. The only reasons to change is: Lower power consumption and, possibly less noise (my reference 5770 is as quiet as a meek church mouse, even under heavy load).

It wouldn't be a big improvement. In some situation you would loose a little performance. As previously mentioned you would also loose PhysX (though that may not be much of a factor in the future). Anyway, you should wait till DX11 is more prevalent and by then the price of two 5850s, or their replacement, should be alot less.

 

[mindless728]

a single 5870 wouldn't be an upgrade, just a sideways movement
for upgrade he would need: 2x5850,5970,2x5870 for it to be worth it
but each of these solutions are $600+, not to mention probably a new PSU

I agree with everyone else it's a sideways move in terms of performance, especially if you have a hefty enough CPU. If you could make the move from SLI to Crossfire without a mobo swap, then likely you do have such a CPU.

What are your system specs? If your CPU is underpowered, the pair of GTX 260's would not be able to keep up with a pair of Radeons. Compare GTX 295 to HD 4870 X2 here: http://www.tomshardware.com/reviews/build-balanced-platform,2469-8.html

As you can see the 5770 is almost exactly the same as the GTX 260 192 core and the 4870 in performance. The GTX 260 216 core is faster by a good 10%.

So either you will get the same performance, or you will get less. If DX11 is really important to you then I recommend waiting for the GTX 4xx series launch in March to see if you can get 2 5850s because they should drop in price. On the whole I don't believe anything less than 2 5850s will be a worthwhile upgrade.
