Of course, installation of a video card involves placing the card in the computer and restarting. No power cable is even required for the HD 4670. Though when it came time to install the Catalyst drivers, as is pretty normal for me, it took a few tries to get the Catalyst Control Center working, and the Catalyst drivers installed. Maybe it's Vista, maybe it's 64-bit Vista, but it has become annoying.
Testing - Benchmarks
I really didn't know what video cards to compare the Sapphire HD 4670 to, I don't own any other "mainstream" video cards. So I looked to see what cards are at the $75-$85 price point. Among the really ancient cards like the FX 5200 PCI and the last generation "mainstream" cards like the 9400GT, 8500GT, and 9500GT, I found that the geForce 8600GT has found its way to that price level. A year ago, the 8600GT was the low-end gaming video card, and sold for around $120. It wasn't a bad card, for the price it was a pretty good entry-level gaming card. My particular model is an XFX factory overclocked 256MB 8600GT.
To check out the performance of the Radeon 4670, I ran a battery of popular benchmarks. To make the comparison interesting, I ran the same tests on a geForce 8600GT. Let's keep in mind that the 8600GT entered the market at about $50 more than the 4670's price.
The HD 4670 performed well against the 8600GT in artificial benchmarks, let's see how it fairs in real games.
