RAM: Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR2 800 ($41)
Even budget builds can afford 4 gigabytes of RAM these days, and this deal for only $41 fits our budget perfectly. 4 gigabytes of RAM is sufficient for any application right now, and for the foreseeable future. To fit our motherboard's 2 memory slots, we chose 2 2GB sticks rather than 4 1GB sticks, though it actually ended up cheaper this way.
Video Card: SPARKLE GeForce 7300GT ($26)
Our budget can't afford the best or newest mid-range video cards, but this 7300 GT is still better than most low-end video cards, especially in this price range. This card uses GDDR3, which is a much faster memory technology than is found on most budget cards, and it really provides a nice performance boost. Being a GeForce 7-series card, it doesn't support directX 10, but it can still play nearly any game if you're willing to turn down a few graphics settings.
