Hey Guys

I just recently (on Friday) got my Sapphire HD5850 gfx card that i ordered, but im a bit confused...
With all of my research on the card and all the reviews i read beforehand, i came across some serious discrepancies between the performance numbers stated in all the reviews and what i actually got on my system.

Now first things first - my system specs:
CPU: Intel Core2 Quad Q9550
MB: ASUS P5Q SE
GFX: Sapphire HD5850 1GB
RAM: 4GB DDR800 Mushkin ram
OS: Win7 x64 (RTM)
Screen: 22" @ 1680x1050
GFX Drivers: Catalyst 9.10 package as per the latest available download

Now as you can see this system is quite ok.
But my experience of the performance of games that are used in all the review benchmarks are quite different.

I could be mistaken here and there with some of the figures, but it is a rough estimate as i did the testing over the weekend.

One performance drop that can be expected would be the difference of my C2Q cpu and the core i7 920 that the review machines use (and to a lesser degree the better ram that they use), but COME ON! The differences as stated in the figures above cannot be right??
I tried various times installing the newest drivers, DX etc. to make sure everything is up to date, and still...

Can anyone maybe give some insight into this?!
I know that its great getting such high fps already, but it should be higher.
