I can decide between 4890 or 5770

I'd go with the 5770 for DX11. They perform pretty close I think but with DX11 you can get Tesslation and Depth of Field - although those are gpu hogs. Even with them turned off, DX11 does a signifiantly better job over DX10 of allowing multi threading on the CPU so you can still get better fps sometimes.

...lol. WTF. Yes, it is used. It's a newer tech but it's used already in AVP, STALKER: CoP, Dirt 2, BF:BC2, Metro 2033, and Battleforge and it is going to be in another 9 upcoming games soon, and any new games will definitely be picking it up since it's the new *** and is supported by ATI and Nvidia.

Features of DX11 include:
1. Uses much less system memory irregardless of how many windows you have open. However GPU memory will still be consumed (so close them windows before playing games)
2. Introduces Direct2D for hardware accelerated 2D. This is a replacement for the software only GDI/GDI+ Windows uses to render 2D objects (like splines). Direct2D is rumored to be ported to Vista and XP.
3. Better display scaling, this is mostly when you have a projector hooked up to your widescreen laptop.
4. Most of the DX11 features are compatible with DX10 hardware.
5. Multithreading support. This means DX11 functions will support multi-core processors.
6. Tessellation - This takes a polygon and breaks it up into even more polygons. This allows for smoother looking curves and higher detail. The best way to think of this, it's as if you took bump mapping or virtual displacement mapping but it's actually real polygons instead of texture tricks. This is the only feature that requires DX11 hardware.
7. Better GPGPU support, if you're into that thing
8. Heterogeneous graphics support - This was missing in Vista but was in XP. Basically you can take two different graphics cards with totally different drivers and have them run at once. But this isn't an alternative to SLI or Crossfire. Meaning if you run a game, it'll still run on one card or the other.


Anyway, the 4890 does perform better, around 5 fps better average or thereabouts. So if that's all you care about then it's a good choice.

and the 5830 it's better than the 5770 and the 4890?

tbh if you get a 5830 u shud just spend more for a 5850 MUCH better, also the dx11 crap, theres NO difference or very minor, its pointless untill next year atleast.

Cant hack what? The game? Im pro at it but it is crap compare to 2142 or even BF2, the game is a console port, its good on the PS3 but crap on the PC, even with the buildings blowing up.

Yes it will be FTW in a years time, im not saying it wont be good its just not very good atm.
