I was having a look at a few systems the other day whats you guys opinion on
a
Asus intel P5GV-MA (LGA775) Motherboard,
Intel 3.4ghz. CPU
1gig X 2 DDR
200GB Seagate sata HDD
not sure on what hard drive to get or the video card yet
If you are referring to this one:
http://www.asus.com.tw/products4.aspx?modelmenu=2&model=793&l1=3&l2=11&l3=237
note that it uses a xxxGV chipset, and what "graphics value"
means, is it has no video card slot. Since you can see
there is a video card slot located on the board, there
has to be a trick. And the trick in this case, is the
PCI Express in the video card slot is x4 and not x16.
In other words, it doesn't have the bandwidth of a
"normal" PCI Express motherboard. For office applications,
that amount of bandwidth is OK, but if you were gaming or
running benchmarks, it is possible the x4 limit might slow
an add-in video card a bit.
If you want to understand how having a x4 video card slot,
versus an x16 video card slot might affect you, this
Tomshardware article used insulating tape, to insulate
the PCI Express signals on a video card, and test the
card with different numbers of lanes enabled. You can see
in the benchmarks, that the impact is not too high, but there
is still a measurable difference between x4 and x16.
If you just want to use the built-in graphics, this will be
a non-issue for you.
The downloadable manual is here:

A normal motherboard looks like this:
Processor
x16 |
Video_slot-----Northbridge---Memory
|
|
Southbridge
| |
PCI PCI Express (mainly x1 slots)
bus
The P5GV-MX looks like this:
Processor
|
Northbridge---Memory
|
|
Southbridge
| |
PCI PCI Express
bus | x4
v
Video_slot
The Northbridge on the P5GV-MX has a built-in
graphics controller, but it is mainly suited to
office applications or perhaps watching a video.
For gaming, a video card is recommended, and it
goes in the video slot.
On the plus side, the motherboard does have three
PCI bus slots, and people generally prefer them, due to
the rich set of add-in cards you can get. The PCI
Express x1 slots still leave a lot to be desired -
we're still waiting to see a sound card that runs
on PCI Express, for example.
