He sure did, it just didn't compute... time to add memory I guess. I don't see why either one wouldn't work as the OP would probably not see any real difference in performance either way. BTW if the system is
32 bit you're limited to (+/-) 3.5 GB of ram. Not enough if you're using a lot of plugins or large VSTis - the reason I finally moved to 64 bit.
As for video cards, the last one I had without a fan always got too hot. I'd go with onboard if possible.
