Windows 7: HIS Radeon HD 5450 Make window aero score lower!

I purchased a HIS Radeon HD 5450 Graphics card as on windows performance score was only 4.3 on aero and 4.5 for games< After I put the graphics card in the score on windows aero went down to 4.1 but he gaming part went up to 5.9 so quite a good increase! The only reason I did this was to increase my WEI as dont play games on PC I have a xbox for that.

I have spoken to the shop who sold me the graphics card and they have told me not to worry about it as the WEI is very un realiable.

What are your thoughts on this?
Thanks in advance for your help

The WEI is just a reference number that gives you some idea how all your hardware is working with Windows 7. If you purchased a new video card to get better video for games the question to you is...
Is your video better or worse then with old card?
I don't worry about my WEI number that much.

The video looks the same to be honest I have watched a DVD and played some HD video only !As I dont have any pc games cant say if it is any better.

What card did you have before the 5450?

I'm not using an ATI card at the moment, but in the past I've seen drops in the WEI with new drivers. The actual performance of the card seemed to not be affected.

I just has the on board graphics from my mother board !

I got a better card and all working great now up to 7.0 on aero and gaming so i am happy
Thanks for all your help
So this thread can be closed

which card did u get to score 7.0 on aero performance?

Sorry for the delay in reply
Here is the link to what I got
HIS ATI Radeon 5670 IceQ 1GB GDDR5 DVI/HDMI PCI-Express Graphics Card - Retail

The only problem I have and I am not sure if it is the card when I boot up if the reciever is not on and the tv screen on does not seem to pick up signal and have to reboot then comes on every time could be some setting some where.
