laptop integrate audio and video quality?

im thinking about replacing my desktop with a laptop. I have a sweet 2.1 speaker system, im sure I can connect these to my laptop at home. how good is the on board audio on most laptops?

also, I know there are different chipsets, but how good(or bad) are the mobile graphic chips? I have a geforce 4 ti4200 with 64MB of ddr ram on my desktop, would I have to spend and arm and a leg to get something even close to this level of 3d on a laptop? I see that the high end video chips are on the high end laptops which i cant afford, im looking at mobile radeon 7500 with 32 mb ram, what does that perform like?

In my experience, the audio out on most laptops tends to be pretty marginal. They tend to pick up a lot of noise/interference from things like the CD-ROM drive motor and whatnot.

If you're a gamer, then you'll find that you need to spend a wad of cash to get decent 3D performance on a laptop. There are some decent mid-priced solutions that will make do in a pinch for playing games, but only some of the newest (and most expensive) graphics solutions out there will have more than 8 MB or so of dedicated memory. And even those that do typically won't give you comparable performance to a mid-level desktop video card.

In a laptop, 3D performance isn't typically near the top of the manufacturer's list of priorities. Battery life and heat dissipation are near the top, and performance suffers at the expense of those priorities.

With a 9000/128 meg = 3DMark2001= 7082 (this is at 1024x768) This is with a Sager 8887 (is NOT a laptop-only a mobile system) PCMark2002=6755,5322,539 (you can notice the HD slowdown here).

Just ran 3Dmark2001 on a Dell 4150 (1024x768) and the score was 916- 7500/32 meg-brems

3d mark was 916??? thats terrible! I'm sort of gathering that a laptop with at least a geforce 4 2go would run UT pretty well. so that leaves the audio, how is it for games(eax,eax2) and for music(snr etc)?

As you know, lap tops are still very expensive. Usually you can custom build a desktop two times better than that of a laptop. All you pay for is the compact size. If you are a serious gamer, stick with the desktop.

For the audio, I've played games on lap tops before and I am very unsatisfied. There is no bass and you play with flat sound, hardly any depth.

My education model Toshy Satellite 1410 has great little speakers (with teenie-weenie sub's!), and you can see the 3D score in my sig - that's with a GF4GO420 and only 16MB Video. That's with a Celery1.5 as well

A real P4 and a GF4GO460 or Mobility9000 (or above) would crank along for you :)

Check out this swank Dell laptop which scored 9376 on 3DMark 2001:

The Alienware high end laptop only scored 7502 in the same test and costs $2,963 as opposed to the $2,417 Dell. This is due to the Alienware using an ATI Radeon 9000 as opposed to the faster GeForce 420 Go in the Dell. Why doesn't Alienware use the faster video card? If it did, it should blow the Dell away. I'm tempted to get a Dell laptop now (not that I need it, I hate traveling; I just lust after the idea of playing strategy games in bed) but I'm waiting for the new mobile GPUs (DirectX 9.0 compliant) which should be out in a few months.
