Hello everyone.
I had recently built a system in October, and got with it a XXX 4890 from XFX. Well, it recently died on me, so I RMA'd it, but in the meantime, I bought a 5770, which I am thus far very happy with. I am considering selling the 4890, keeping the 5770, or possibly selling both of them and upgrading to a 5850. Is it worth it to get a 5850 or just wait until I need to upgrade and xfire with another 5770? I have to get a different 5770 later anyways because I want to eventually do eyefinity, and mine did not come with a displayport (poor research, quick decision). So I would sell both the 4890 and 5770, get another 5770, and eventually get another 5770 for xfire. How important is the 128-bit vs 256-bit memory?
I am pretty sure you need the same manufacturer and model of cards to xfire, right? Or am I out of my mind? Any advice is appreciated, I am kind of stumped with what to do here. Thanks!

If you are happy with the performance there is no need to upgrade specially if your resolution is 1680 x1050 or less. But if you want to upgrade the HD5850 is a solid choice.

you don't need to have the same make to CF, just the same GPU. You can even CF an OC 5770 and a factory clocked one (although both cards run at the slowest settings).

If the 5770 does the trick, I would just CF at a later date when you need more performance; or upgrade to a 5850 or newer card.

Tough Decision. Personally i Would Go for The 2x 5770 But only if your MOBO supports 2x16 bit PCIE Channels.
Other wise The 5850

Honestly, I would try and get the 5850.

The 5850 would give me a little more power than the other two you listed so that I wouldn't have to upgrade as soon as if I had the others.

Also when it is time to upgrade, the second card should be cheaper and the power from both of them would last me a little longer as well.
