I think its a great idea, some people dont realize it but all that heat coming off your videocard can really increase your CPU temps. I know of an Athlon 1.4 system i put together for someone at work which i got running with a GF2 Ultra (very hot card). Anyway the CPU temps would ilde around 47-50c (it was not a very well cooled case, just an IE, Excel comp anyway). So after exchanging the GF2 with an old ATI rage2 vid card i found the CPU idle temp dropped to 40c, 43c at most.
But to bad they didn't at least put Heatsinks on the ram...
