When shopping for a new video card, you'll likely
fall into three categories... non-gamer, casual gamer, and serious
gamer. Non-gamers will either pickup the cheapest card they can
find, or use whatever is bundled or integrated into their current
PC.
Casual gamers on the otherhand can probably get
away with a $100 to $150 card. In this price range, there are
a lot of choices as you'll find dozens upon dozens of low to mid
ranged cards fighting it out for your cash. Framerates are important,
but so is the bottom line, and blowing half a grand on a video
card is probably not a priority.
If you're a hardcore gamer, you'll have to expect
to pay a little more as the latest action games (as well as almost
every other category from strategy to role-playing) are demanding
more out of your hardware than ever before. At this price point,
the choices are a little more clear cut, as both NVIDIA and ATI
have enthusiast level products aimed directly as this segment
of the video card market.
Today, we'll be taking a look at the ASUS
Extreme AX800XT, which is an enthusiast level PCI Express
part. As you can gather from the name, this video card is based
on ATI's flagship X800 XT VPU. To checkout the rest of the card's
capabilities, refer to the ASUS link, or read the specifications
below.

The ASUS Extreme AX800XT
The ASUS Extreme AX800XT is packaged in a huge
box with some nice artwork, and a listing of the card's specifications
and capabilities. Inside, you'll find a driver CD, productivity
software (full list here),
a manual, a plastic CD case (containing most of the software)
and Deus Ex: Invisible War.
In terms of hardware, other than the AX800XT video
card, ASUS includes a 9 Pin S-Video to composite VIVO cable, two
DVI-to-VGA output adapters, a 6-pin power splitter, and a webcam.
The webcam is USB based, and is capable of 300K pixels resolution.
The ASUS Extreme AX800XT is a "standard"
sized card, and should have no problems fitting into full height
systems. The ATI Radeon X800XT VPU is a native PCIE processor,
and is clocked at 520MHz. This is ATI's topflight part, and has
16 pixel pipelines with hardware support for DirectX 9B and Shader
Model 2.0.
Cooling is provided by a large copper heatsink and LED fan combination.
The card itself is very heavy, mostly due to the cooling apparatus.
Although it is not as large as some NVIDIA 6800 coolers, the cooling
on the Extreme AX800XT is not quite a one slot cooling solution.
Depending on your motherboard, there may not be enough clearance
between the PCIE 16X slot and the adjacent slot.

As we can see above, with our ASUS P5AD2 Premium, the fit is
pretty tight.

The Extreme AX800XT uses Samsung's K4J55323QF-GC20
GDDR3 (Part number K4J55323QF).
According to Samsung's specifications, the BGA ram is rated at
500MHz (1GHz DDR). The AX800XT, while a full fledged X800 XT,
is not a Platinum Edition part, as that version of the card uses
560MHz ram. ASUS clocks the AX800XT at the maximum ram speed,
so at the moment, we're not holding our breath for overclocking
potential.

A 6-pin power connection is used to give the extra
juice needed to operate the card. Using the 6-pin splitter, simply
plug in two 4-pin Molex connections, then plug the splitter into
the card.

For your input and output options, moving from left
to right is the secondary DVI output. Next to it, we have the
video-in, followed by the primary DVI. If you have analog monitors,
you can use the two DVI-to-VGA adapters instead of the digital
outputs.
Test Setup
ASUS
P5AD2 Premium: Intel Pentium 4 560 (3.6GHz), 2 x 512MB Corsair
XMS5400 ProSeries DDR2 (4-4-4-12), ASUS Extreme AX800XT, 160GB
Seagate 7200.7 SATA, Windows XP w/SP1, Catalyst 4.9.
We'll be using FRAPS to record framerates in all
our tests, playing the game as anybody would (trying to stay alive),
firing weapons, dodging attacks and so on. Unlike our past video
game tests, all benchmarks will be done with the audio "on",
as we're trying to illustrate real gaming experiences, and I doubt
any of our readers mute the audio during gameplay.
Test Software will be:
Doom 3 - Making good use of the BFG, rocket
launcher and plasma gun (the most graphically intense weapons),
we'll be killing demons on the map Delta2a. We'll also be demonstrating
multiplayer performance.
Far Cry - Another graphically intense shooter,
we'll be fighting baddies in the Swamp level.
Painkiller - If you're looking for flat-out
action, this game provides it. The City on Water map will be used
for benchmarking purposes.
The driver settings were manually configured for
AntiAliasing and Anisotropic Filtering (on or off), and set to
"Quality". All games were set to their highest allowable
game settings. Unless otherwise stated, all games will be played
at 1280x1024.
