PCI-E Video Card
PC gaming promises the potential for constantly improved gaming experience due to the
inherent upgradeability of the hardware. It can be an expensive hobby as games and hardware push and shove each other to greater performance. To play the latest games smoothly and consistantly at high resolutions
requires a gamer to stay on top of current technology, always eyeing the next
But what about the rest of us? With the demands of work, family, and what have
you, many people just don't have time for PC gaming, or if they do, only for
brief intervals to unwind. There are also those who don't have high resolution
monitors, and casual gamers who prefer to play games at lower resolution in
windowed mode while multitasking. For these people, the cost of a high
performance video card isn't justified. There's also power consumption,
and noise to deal with high performance graphics cards are usually pigs in both regards.
The Radeon HD 4670.
What is ideal for the casual gamer is a cheap, video card with enough
oomph for them to enjoy the occasional gaming session, while staying quiet
and energy efficient when not in heavy use. With the Radeon HD 4670, ATI hopes
to fill that need. It is perhaps the fastest and most powerful budget graphics
card released, with a high clock speed, fast GDDR3 memory, and a whopping 320
stream processors all in a nice tidy package. Our sample also supports
DisplayPort, a new digital interface standard that is license and royalty-free. While
the standard has many technical advantages, few devices support DisplayPort
(Editor's Note: This entry on the Direct2Dell blog site provide a succint summary of The Truth About DisplayPort vs. HDMI. The author notes, in essence, that HDMI is intended as an external consumer electronics connection for HD TVs, while DisplayPort is the digital interface for connecting flat-panel displays to computer systems. The latter supports higher performance as a standard feature every 6-foot cable supports 10.8 Gbps. Please read the linked article for more details.)
