My MSI HD Radeon is not installed properly I believe...

[ronin12]

In Steam and using lspci it showes:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850] (prog-if 00 [VGA controller])
 Subsystem: Micro-Star International Co., Ltd. [MSI] Device 2730
 Flags: bus master, fast devsel, latency 0, IRQ 47
 Memory at e0000000 (64-bit, prefetchable) [size=256M]
 Memory at f7e00000 (64-bit, non-prefetchable) [size=256K]

 Expansion ROM at f7e40000 [disabled] [size=128K]

How to fix this please?
I tryied to inastall drivers (additional drivere update and other).
I followed instructions on:
https://help.ubuntu.com/community/BinaryDriverHowto/AMD

I believe the same was on 12.04 LTS becouse I had lags during CS on Steam as I do now.

Kind Regards
Wojtek
