I am using an XFX x16 2.0 4670 card on an Asus P5Q-E board. The card is limited to x8 2.0 bandwidth due to other cards, but occupies the primary x16 slot (other cards are a couple of RAID cards the knock primary x16 2.0 down to x8 2.0). It is driving a 2560x1600 and a 1920x1200 DVI monitor set. Does a 4.8 Aero score sound right? Gaming comes in at 6.4. Processor and memory at 7.3 and primary HD (an SSD) at 7.0. Just wondering why Desktop Aero comes in so low, or is it because it is handling such high resolution? Or is it because the card only has DDR2 memory? I'm not a gamer, so it's not like it's the end of the world or anything, but I was curious. Thanks for any info.
