I wouldn't even get this card, just spend the extra 50-75 bucks and get a 5770. I have one in my rig and it hasn't even broken a sweat on any game.

How does it compare to the HD4850?

The HD4850 performs significantly better in games than the 5670. The 5670 is just a tad faster than an Nvidia 9600GT and falls way behind a 9800GT. The 512MB version of the 5670 outperforms the 1GB version even at higher resolutions from what everyone else is saying.

The DX11 compatability is a mute point because any DX11 game will smoke the 5670 badly. If looking for a new card, I would go with the simarily priced 4850, no doubt about it.

I'm running a single HD4850. I've considered adding a second HD4850 (if I can FIND another Visiontek card identical to mine) but with Windows 7 and Direct X 11 here, I'm open to alternatives.

I had the 4850 myself (and only paid $85 for it brand new, XFX). I don't know what resolution you are running, but honestly, if it weren't for the fact that I sold the card to my cousin, I'd still be using it right now. It is a good card! You can ride out the next year with that card still I imagine. After Nvidia releases Fermi and AMD responds with its new cards, you can then pick the best of the litter. I don't think upgrading atm is completely worth it (even for DX11).

Also, in regard to the original question, the 4850 > 4670. The 5750 is more of an equivalent to the 4850, and even then it is slightly slower than the 4850. This card is not a real "upgrade" from the 4850, sure you get additonal features, but you are losing muscle in the process.

Newegg has plenty of 4850's for sale. Are you sure you have to have the same exact card from the same maker to X-fire them? I know with Nvidia, you can have two GTX xxx from two different manufacturers with two different clock speeds, like a stock card and an overclocked card, and you can SLI them no problem. The cards will just match the slowest clocked card and run. Something to look into if your system actually needs two GPU's to push your resolution.

Right now is actually one of the few times I'd even recommend going more than a single GPU because of the state of the GPU market.

Great.  I finally get a current gen game for the first time in years, Fallout 3, and it runs choppy as hell in 1920x1080 even with two Visiontek 4850s with CrossfireX turned on.  I bought them almost a year and a half ago and when they finally put out brand new single slotters, they're not as good.  The hell is that?  I'd be less opposed to a double slot taking up the space of two in crossfire if the performance was vastly superior and if they weren't almost always obnoxiously noisy.
