GeCube Radeon HD 3850 X-Turbo III 512 MB Review
AMD's new Radeon HD 3850 has been a major upgrade in both performance and efficiency. GeCube has taken the reference design and increased the clock speeds. They also doubled the available memory to 512 MB GDDR3 and use a two slot cooler on the card. But can this yield enough performance to warranty a $30 price premium? We compare it to 17 other video cards.
