It all depends on the review. Like it has been mentioned, the later reviews seem to put the 5770 right on par with the GTX260 and 4870 for most games. For instance, the latest 5770 review from guru3d.com paints a interesting picture. Some average frame rate examples.

Crysis Warhead - 1920x1200 - Gamer details - 2xAA - DX10

4870 - 26 fps
4890 - 30 fps
5770 - 27 fps
260 - 28 fps

Call of Duty MW2 - Max details - 4x AA 16x AF - 1920x1200 - DX10

4870 - 68 fps
4890 - 77 fps
5770 - 72 fps
260 - 74 fps

Far Cry 2 - 1920x1200 - 8xAA 16xAF - High Quality - DX10

4870 - 32 fps
4890 - 35 fps
5770 - 33 fps
260 - 40 fps

The fact that the 1GB HD 5770 performs about on par with these other cards, uses way less power, runs cooler, quieter with the new egg coolers, overclocks great and can easily be found for under $150 if you look around a bit makes it a pretty good choice IMO.

time*(5770 + two more monitors)^365 = 0 sunshine

OP, i upgraded from an 8800gt to the 5770 and i can tell u it's a great upgrade for 1680x1050.:) it provided me w/ a 60-80% increase in FPS depending on the game, and for $150 u really can't go wrong, especially after selling your 8800gt for $50. really great upper mid-range card! w/ the recent driver updates it performs on par w/a 4870 now. Supposedly in the future it'll see even more performance increases w/ newer drivers. They also overclock really well, so if u must have the extra 10% performance of a 4890, just overclock em.

While at low resolutions, the HD 5770 is on par with the HD 4870, usually the HD 4870 is slighly faster, and as the resolution increases, and anti aliasing is used, the gap widens. But the HD 5770 offers in average the 97%-99% of the HD 4870 performance with much less power consumption and much better overclockability, buying an HD 4870 today is pointless unless if you could buy it for less than $130.

The argument that DX11 impacts more the performance compared to DX10 is a moot point, because Dirt 2 doesn't have a DX10 path and can't be used as a valid point. The performance impact going from DX9 to DX10 is the same as going to DX9 to DX11, DX11 is simply a subset of DX10.1 which proved to improve the performance specially when anti aliasing was used compared to DX10.0. The only thing that can eat a lot of performance in DX11 is the tessellation if it's used improperly like in the unigine demo, which was used almost everywhere unnecessarily.

Sup with the 5890 and 5830. Everybody in this thread and forum seems to have tested this card but hell, those cards do not even exist yet so stop comparing to those 2 cards.

I'd go with the 5770 for DirectX 11, otherwise the HD 4870 or 4890 depending on the price. The HD 4000s are great budget cards right now, especially given that there's only three DX11 games out now AFAIK.

What resolutions are you talking about?

The OP is using 1680x1050 and is considering going to 1920x1200. Looks like in newer reviews, the 5770 beat the 4870 most of the time.

What I see there is the opposite, the difference is small though, and sometimes is even a wash.

That is an older review, using catalyst 9.9 and even catalyst beta.

Newer reviews using Catalyst 10.1 or even 9.12 show the HD5770 at leat on par with the HD4870 and the GTX260. Just do a web search for "powercolor pcs+ radeon hd5770 review" and check the results ibn those newer tests. Guru3D and tech-powerup had very comprehensive tests, and the 5770 comes ahead the majority of time.

You can also check the reviews of the HD5670, where the HD5770 are already scoring on par with the hd4870 and the gtx260 :)

PS. Like many other ATers, I have that powercolor radeon 5770, it is a great card!
I even got a few more, so now all the children's machines have upgraded firepower... I am sure Barbie Island princess has to be shader intensive :p :p

Yeah, I would go 5770s. I have two 4870s and they are awesome, but they are loud and hot. 5770s give you equal awesome without the loud and hot.

Seriously...

it has been posted multiple times to check newer reviews. Even in my post which you quoted.

And your point is? It isn't like with newer drivers, magically the HD 5770 will perform twice faster than the HD 4870, after all, both shares the same architecture in the low level like stream processor layout, and have the same 800 stream processors. Driver updates may improve the performance in scenarios where the game may take advantage of the additional cache or tweaks that Juniper offers.

That's the point... the HD5770 has gone from being slightly slower to being slightly faster due to driver updates...
No one is claiming that it's magically twice as fast, just that it's gone from slightly slower to slightly faster.

They are in the same ballpark, anyway. For the same/similar price I'd go for the 5770, as it should be cooler/quieter. (I have a 4870 and when I'm not gaming I need to turn the fan down below 30%, or it's annoyingly loud.)
