ATI HD4850 xfired vs HD5770

Here's my setup:

Antec Three Hundred gaming case
Asus M4A78-E mobo
AMD Phenom II X4 940 3.0ghz
Corsair 4GB DDR2 Dual Channel 1066hz
WD 500GB HDD 7200RPM
2x Visiontek HD4850 512MB GDDR3 xfired
Ultra 600w PSU

I am considering a GPU upgrade in the near future for an 1GB HD5770. Problem is, from what I researched, forums stated the HD4850 crossfired will outperform the HD5770 but I'm not sure if they are referring to the 512MB in this case I currently own.

I"m trying to get some help on making a logical and money saving decision on whether to keep my HD4850's or get the HD5770 or upgrade my RAM to a potential 6GB DDR2. I usually have issues in trying to get a game, World of Warcraft, to run on 1920×1080 and Ultra quality settings without choppy framerate issues.

Any help would be appreciated.

Note: I"m not interested in OC'ing both cards at the moment.

A 5770 is not enough of a upgrade.
It would be like going from 1 4850 when your crossfire does not work well to a 4870.
You would want to consider at least a 6850, they are creeping up in price it seems.
The msrp is 180.00
Those are 40nm gpu's they o/c much easier than older gpu's.
The 6850 comes at 775mhz, but you can easily o/c to 850-875 , which would give you better performance than your 4850x2 even at its best.

If your not buying online , what is the price difference for you , from a 5770 to a 6850?

My budget concerns of purchasing a single HD5770 and then another in the future to crossfire but I will consider a single HD6850 as a decent alternative. I buy online only for the reasons that most retailers sell it for near MSRP price.

Any brands I should look out to buy from for the HD680?

This is one of the quieter ones, and also the more higher performing heat sink.

Besides that one, I like the Saphire http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Your getting near 5850 speed with the 6850's, if you o/c a little.
The 6850 is a slightly altered 6870 which they clock at 900mhz, this is why most 6850's easily can be o/c for more performance.

Thanks. I don't plan on OC'ing the 6850 anytime soon if I might consider just OC'in the twin HD4850's in my system now just to get some modest results.
