Is the 650d considerably bigger than the 300r? His computer desk isn't very big, it's about same size as mine ( considering the place in which the case will be put ), is it larger than the cougar volant? ( The case I currently have )? If so, by how much?
P.s : Also, if the second GPU is disabled by software, does it still receive power as if it was idling? And does software disabling the second card make the first card run at full x16 rather than the x8 it'll run at in SLI mode?
