If I were to win the ebay gift card, I would definitely be getting a new computer. I enjoy playing computer games, and I cannot play many with the computer I currently have. Here is the computer I would choose
HP Pavilion HPE H8-1320T Desktop, Core i5 3GHz, 6GB Ram, 1TB HD, DVDRW, WiFi | eBay
With the little bit of left over money I would pick up a card or two that I was interested in.
