Would the ATI Radeon 7000 be a good choice to upgrade the original Video card? Will it make a significant difference in performance for the investment? Or would there be a better choice. I understand some of the cards are not compatible with the power source. Also upgrading Hard Drive Controller to a 133 mb/sec PCI have a noticeable change in speed for the cost. If so what would some suggestion of the list. Thank all of you for your comments that yu care to offer. Russell Strodtbeck
