New Radeon 5000 or 6000 series, best option?

Just had my XFX Radeon 4890 burn out, literally. Need a replacement soon and searching but I really don't see the difference between a lot of these cards besides the price. Hoping for some elaboration or suggestion.
My 4890's stock core: 850MHz / mem: 975Mhz, for some games OC'd to 900Mhz/1000MHz. It ran just about everything at the highest possible settings at 1080p. I think Metro 2033 was the only one I ran at medium settings and even that wasn't too bad at the highest. I definitely need something that can handle the same for less than $150, cheaper the better.
I've found a few I'm thinking about:
Sapphire 5850 XTREME - $149.00
Sapphire 6770 - $129.98
Sapphire 6790 - $149.00
XFX 6790 - $152.55 after $10 rebate
Gigabyte 6850 - $163.98 after $10 rebate
MSI 5770 - $99.99 after $30 rebate *the one I'm leaning toward just for price
The 5850 I think is the only one with 1440 Stream Processors but has the lowest core speed, does this make much difference? A couple of them were 128-bit while others 256-bit, how much does this effect exactly? Is there any difference with these card's DX11 effects? 3D support? Manufacturer's customer support differences or problems with rebates?
Anything of significance here or that you all know of, please let me know!

The HD5850 is the best card you listed and the best deal imo. If you are ok with rebates the HD5770 is a good deal too but it will be a downgrade from your HD4890. It is more on par with an HD4870. FYI in general the HD5850 is about 50% faster than the HD5770 which exactly matches the price difference I guess. The low core speed on the HD5850 is actually good because it leaves a lot of overclocking headroom. Those cards can often get up to 1ghz if you bump up the voltage which is an impressive 38% over reference.
The HD6850 is the other card you listed that would be an upgrade over your HD4890. It is a good deal but it just can't match the HD5850 at $150. The HD5850 is faster by approximately 10% on average. The HD6000 series does have improved crossfire scaling and tessellation performance but it is just enough to make the HD6850 catch up to rather than surpass the HD5850 and just in those specific areas. The main advantage of that card if it is important to you and worth the extra money and performance hit is that the HD6000 series has HDMI 1.4a which has better 3D Bluray support.

Yep, like jyjjy said, the 5850 is a great deal and a great overclocker.
