I installed Windows myself and it was a clean install not a upgrade also my other computer I had before this one was done had XP Home installed and this video card and it worked great fast but as soon as I installed this card in this computer and installed Windows 7 it ran slow at times most of the time it was just a slow boot time and some programs would be slow to load IE, Windows media player, Firefox, IE8, AVG anti virus programs like that are always alittle slow to load and also my online games the run on flash player don't work to good but worked fine with XP. opening folders like my computer or other folders are very fast about 90% of the time.
Also I only have the minimal programs running at start up only about 2 programs running. and after startup I am only using about 14 to 20% of system memory and about 4 to 8% of the CPU
The video card I plan to buy today is the Sapphire Radeon HD 5450 1GB DDR2 I wonder if this card will make much of a difference?
