Just a comment, the 5750/5770 are mid range gaming cards. Not mainstream cards. If you are looking for a mainstream card and are NOT gaming, you do not have to spend $150-$180 on a card. $50-$100 is sufficient.
@ Dansak001: Installing a $180 gaming card is a waste of your money if you only need to use the system for Excel/Office or watching even Blu-ray movies: A $60 HD4650 will be more than enough, even with dual monitors for those uses.
So we really need to know: The monitor resolution/s and the system use/s before we can give any meaningful advice.
It would mainly be for work, watching video and some gaming but not the superfast action type ones although I would like to be able to play them at times but they could run medium paced..
The other thing I noticed in the manual is that is says the Graphics slot has a max of 150Watts (PCI-E x16)
My current card is NVIDIA Quadro FX 3450 which gives me 3D business and gaming rating of 5.1

As an aside, does anybody know if above processor can be replaced by faster one, using the same slot?
