Question about my 5770's memory

Some system memory is also dedicated to graphics too, though not often used. That's what I was told.

it could be taking into account your integrated graphics chip, you did turn it off in BIOS right?

Do I want to disable my onboard graphics card? Is it really a necessity?

if everything is working fine then its not a necessity. it can cause issues in some motherboards

Right^
Sometimes it may cause trouble,(have seen some users reporting it) but if its working fine for you,then there is no need to disable it

Yea, I have an AMD Phenom II X4 955 Processor with an Asus M4A78T-E motherboard and it's been working great with no problems since I installed it yesterday. This video card is like 10 steps up from my 3300 HD onboard card. I ran that Windows Experience Index and my 3300hd scored a 4.7. This new card scored a 7.5 out of 7.9. Now the only thing I need to replace is my hard drive which scores a 5.7. Any suggestions for a nice cheap but fast hard drive?  

most had drives score just 5.9. unless you are dying for a SSD drive or your current HDD is having issues/maxed out I would not worry about it.

WEI isn't a good way to determine your performance, don't worry about the scores.
Every time i upgrade my system, i always get a score like 5.7-5.9 for my HDD.(For each upgrade, i put a faster HDD in my system but the score doesn't change much)
