After discussing the theory of PC cooling, in Part One, we now move on to technology and implementation, discussing case fans, CPU coolers, and thermal grease. We even wrap up with a recipe you can use if you fail to cool your PC properly.

Today we put four factory-overclocked GeForce GTX 580 cards to the test: Gigabyte’s GeForce GTX 580 Super Overclock, MSI’s N580GTX Twin Frozr II/OC, Calibre’s X580 Captain, and Zotac’s GeForce GTX 580 AMP²! Edition. Which one is worth its premium price?

We gave the GeForce GTX 560 Ti a thorough evaluation at launch. But Nvidia was perhaps most excited about some of its partners were doing with GF114. And so, we set out to find customized boards. Our search lead to five factory-overclocked alternatives.

We received a trio of 1000 W power supplies priced between $200 and $300, so we ran them through our usual suite of tests to see if they really live up to their 80 PLUS Gold certifications. Surprisingly, all three hiccuped during efficiency testing.

Gamers demand a lot from their computers, starting with the PSU. Therefore, almost every PSU manufacturer sells products optimized for gaming PCs. We introduce ripple and noise testing in this roundup to further improve our power supply evaluations.

New benchmarks, new test methods, and new hardware mark exciting updates to this month’s System Builder Marathon. Today, we cover the most exciting part of all: the value competition. Remember, we're giving all three systems away, so enter to win them!

Anyone interested in Nvidia's GeForce GTS 450 has a keen eye for value. But many enthusiasts still want the best performance they can afford. In today’s test, six factory-overclocked models challenge a standard-speed card in performance and value.

Display spanning is quickly becoming the high-mark for serious gaming machines of all budgets, with more powerful cards allowing higher resolutions. Yet, as panel resolutions higher than 1080p become harder to find, do we really need more than two cards?

Happy with Nvidia's GeForce GTX 460, we invited a dozen of the industry's top graphics companies to show off their unique interpretations of the card. Nine responded with what they feel are exceptional products. Can they get any better than reference?

The GeForce GTX 460 has already proven itself an excellent value as a single card, but can two of them offer superior performance at similar cost to Nvidia’s flagship GTX 480? Let's just say that there's a good reason to buy an SLI-compatible motherboard.

Manufacturers really love the first Geforce 9. The graphic chip is fast, the cards are inexpensive, and some retailers offer more than ten variations.
