What motherboard did you use?
Did you use a driver cleaner after uninstalling the previous cards?

lol, mind explaining how you ran Crossfire on an EVGA 750i SLI board?

EDIT: It would obviously explain why you got better performance on a couple GTX 260s in SLI. Because naturally only 1 5770 is going to work on your SLI board. So, the poor performance came from: You game at 1920x1080 / 8xAA, and the 5770 is about on par with 1 4870 1GB. I had the 4870 1GB, and in BF2142, I would max it out in 1920x1080p / 8xAA, and pull around 70-85fps. Hence you getting around ballpark that. Problem solved, brah. It's not the 5770s problem, it's YOU trying to run CF on an SLI board.

Anyways, it's probably due to crappy drivers, the game not being optimized for crossfire,... did you try any other games on them?
And I think you made a bit of a quick decision to swap them for 260's already, now we can't solve your problem with them..

thats your problem the 750i or any nvidia based board does not support crossfire only SLI
EDIT too slow. you need a Intel or AMD chipset to crossfire. Nvidia locks their chipset to SLI

Yea I realized now, however even with 1 card running, it should have been able to run 2142 maxed out and just as good as a 260.
Also isn't is a big odd that you can run crossfire on a SLI board?

Me as well.

Nope. The chipset has to support it. Only Skulltrail and X5-series and P5-series Intel chipset can do both crossfire and SLI, AFAIK.

Why would Nvidia let its competitor's proprietary technology work on boards using *their* chipset?

Were you running it on the same graphics settings ingame? That would be why it didn't look better. Upgrading your graphics card doesn't instantly make games look better or something.
And we can't explain why the single card didn't perform that well since you already got rid of both the 5770s. We needed to help you troubleshoot them.

Honestly the only difference I saw between the 3650 and 5770 was increase in FPS amd smoothness, the game did not look any better. Why do you guys think that? |

It's a bit of an old game.
