HD4870 XFX hash rate

[Nizace]

What Hash Rate should i be getting on a HD4870 XFX version?

Im Using BFGminer/GUIminer and only getting about 22Mhash. Ive not changed any of the default setting on any of the miners.

My PC is on all day anyway so im not bothered about cost to run.

My specs are :-

Intel Core2Duo E8400 3Ghz
Radeon HD4870 XFX
4GB Ram
Windows 7 x86

around 80 to 110 mhash/s according to https://en.bitcoin.it/wiki/Mining_hardware_comparison

Can you identify which model is yours from the website, if so, try using the suggested flags.
