my friend's spec is this:
mobo : P5Q-Pro
proc. : core 2 duo xxxx 3.0 ghz
ram : 4 gb
vga : gigabite 9800 gtx+ 1gb
he installed windows 7 64 bit professional, and the latest nvidia driver.. and then we enter dxdiag to make sure the 4 gig ram, and it was all good.... now the strange thing is the approx total memory of his gpu is now 2000+ mb... so what happened? as far as i know you cant increase a discrete gpu's memory buffer... anyone knows?
