Good catch, I was assuming he'd go with the earlier advice to upgrade his power supply.
I looked up some power supplies upon your suggestion and found that I could get 400W for a reasonable price, but a $30 PSU on top of a $50 card wasn't as tasty as just a $30 card.
Again, thanks for the help and info, guys. Looking forward to raining aircraft parts all over the countryside real soon (mostly my own
)
