Excerpt: The recipe: Take two of the fastest GPUs on the planet capable of running DirectX 11, specially chosen for their low voltage leakage. Toss in two gigabytes of high-speed GDDR5 memory. Mix all ingredients into a card with high-end Japanese solid capacitors and a souped-up thermal dissipation system. The result: the XFX Radeon HD 5970—a GPU so yummy, you may even go back for seconds.
Pros: Incredible gaming performance; very low idle power usage; XFX's excellent warranty.
Cons: So big you need a huge PC case to hold it; pricey; eats power at full bore.
