okay. 40 cores is that good or bad? Anyway can it play bf2 at
medium settings? And how can i switch between it and a discrete
graphics card?
BF2 at medium? No. Low, at 1024x768, yes. Trust me,it's not fun
to play games on an IGP. I've tried that before with my HD4200.
40 cores on ATi: Sucks. 40 cores on NVidia: Decent.
Basic guideline: Divide ATi's cores or stream processors by 5 to
get a rough equivalent to NVidia's cores. 40 ATi cores is about 8
NVidia cores. Which is why you see the HD5870 having 1600 cores and
GTX480 having 480, yet the GTX480 still beats the HD5870.
Note: You can only switch between the IGP and the dedicated card
if you have a CERTIFIED GPU AND MOTHERBOARD. ATi's PowerXpress only
works on LAPTOPS, so no go for desktops. Your discrete graphics
card will ALWAYS be active.
