Is an upgrade from an ati 4850 to a 5770 worth it? Will i really feel a huge performance jump? I am currently playing crysis warhead, nfs shift, and I am hoping to play modern warfare 2 and left for dead 2. Has anyone else done this card swap? Some insight would be great! thanks!

You should see a pretty good performance increase from the 5770. It'll perform as well as a 4870 1GB, although at higher resolutions you'll definitely need more memory.

The only real bonus over the 4870 that the 5770 has is that it's DX11.

I dont think it is such an upgrade. First thing i would consider is a 5850

And it scales way better in crossfire, And its 40nm and overclocks very well.

And uses much less power, And idles lower, Uses 100w @ load.

I'd like to say hell yea its worth the upgrade!

I used to have a single 4890 and honestly this single card creams it in all of my old games!

There will be a difference similar to going from a 4850 -> 4870

Whether or not that is significant is up to you. (look at some benchies)

5770 is still slower then 4870 1GB and only beats them in CF. I moved from a 4850 512MB -> 4870 1GB and did not notice much difference. I would not upgrade to anything under 5850.

The power consumption is not really an issue unless your rig runs 24/7. My 4870's idle @ 48C.

As for scaling, well mine scale VERY well. I get almost 2x the FPS when I crossfire them.

And from all the benchies I've read 2 4870 1GB's usually beat out 2 5770's. Not by a huge margin but enough to be noticeable. However, most of those benchies were run with older and immature drivers. Perhaps the new ones will make better use of the hardware.

I went from a 4850 to a 4850x2, and I saw a solid performance jump right there. I can max out crysis at 1680x1050. Not that that's really that cool anymore.

I would not make the upgrade unless it is for another benefit offered by the 5770 other then performance. For example, I went from a 4830 to a 5770 in an HTPC due to the significant lower power consumption. But if you are just basing your upgrade on sheer performance, I would not recommend it.

Not worth the money. That would be a big investment for a subtle increase in performance. What games does the 4850 struggle with at 1080p? Mine tears through stuff. 2 of them are brutal.
