I actually wanted to get the ATI 9000, because pricing is the same but performance is much better than the GF4.  However, I'm an impatient man, and Dell was out of stock with expected restocking date...get this...in MAY 2004.  I expected better than 3700 3DMarks, at least 4500 with this card.  I looked on the benchmarking profiles, and I saw a few i8100s with the Gf4 clocking in at 4000-4500 range.

Okay dude, I myself have an upgraded I8000 with an ATI Radeon Mobility 7500 64mb (ATI M7).

Don't expect steller performance and it realy depend is the 1.4ghz p4 or a 2.6hgz p4... on the 8200  I would sell the gf4 440 go and get and ATI Radeon Mobility 9000 (ATI M9) becuase it runs faster and IS COMPATIBLE WITH DX8 unlike the gf4 which is more like the ati radeon mobility 7500 (both have only dx7)  You can try www.omegacorner.com 's drivers modde nvidia driverrs which work with all geforce!  You just slide this bar in ur advanced display options and you can over-clock, but i dont realy recommend this and i have never had the currage to do so my self  Also the I8100 cpu has 512k cach and the 8000 cpu has 256k cach so to see aprox what to expect try benchmarks for an 8100 ati 7500!   Make sure the 8200 u saw was not running the ati m9, superior card!

Oh ya the gf4 440 go is equivelent in the desktop world to a geforce4 MX series which is like budget stuff kind of...  It does not hve the pixelshader and niether does the ati 7500, but the ati 9000 does.  heres my macro about I8000/8100/8200 video cards  thhe best cards in my opinion are the ati m7 and m9!

64mb nVidia Quadro4 700 Go GL ($319: Dell Spare Parts and have to tell dell you have a percision m50) Best out there for the 8000/8100/8200 C800/C810/C840 M40/M50 series dell laptops: it is basicaly a nVidia GeForce4 4200 Go (mind thats a mobile version of the GeForce4 "Ti" 4200 i believe: way ahead of the cheaper "MX" Series) The quadro is a workstation card with extra feature for working with programs like CAD) It is a Direct X 8 support card and will work with the newest games. this has "pixel shader" Transformation and Lighting T&L engine also need in many new games

64mb ATI Radeon Mobility 9000 (ATI M9) ($129: Dell Spare Parts) A Close runner up to the Quadro4 700 Go, the ATI 9000 still has valluable Direct X 8 support for running the newest games and future games and yeild performance close to that of the Quadro4 700 Go! There are a few incompatability isues though with a few games: It runs slowly with GTA 3 but works fine with vice city: there is a hardware tweak to fix this probles, i believe. The other game is Rainbow Six:3 Athena Sword expantion which states it doesn nto support ati's mobile radeon line, this may be flase or corrected in patches. 2 small games of which at least one has fixes. It also has the valuable "pixel shader" Unlike the radeon 7500 (origional radeon on speed) this is a varient of the different 8500 core.

64mb nVdia GeForce4 440 Go ($100 Dell Spare Parts; $100 or less on ebay) This is efinately a step down from the ATI M9! This is equivelent to the GeForce "MX" kind of a budget line of geforce not so great, and it does not have the pixelshader, though required by few games, it makes everything look better. You may have to drop bellow 1024x768 to get decent perfomnce on the newer 32mb requiring games. On the up side it offers the Transformation and lighting (T&L) Engine. It is also a step up from the ATI M7 in general though it does nto offer more features. It only offers Direct X 7 compatability so future games may be at stake Over all its worth the extra 30 bucks for the ATI M9! It is compatbile with almost all current games that don't need pixelshader

64mb ATI Radeon Mobility 7500 (ATI M7) (maybe $80 from dell part and $50-60 on ebay) This card is best put as the origional radeon on crack! The M7 offers the Transformation and Lighting Engine (T&L) This is a big boost from the GeForce2 Go with 2x the video memory and better stability and performance! I would opt for this from ebay over the GeForce 4 440 Go just because the performance drop isn't huge and the price drop is! The 7500 offers no pixel shader and you may have to go bellow 1024x768 on those 32mb req. games (personal experiance) This card is a way better value than the gf4 440 go with similar performance at half the price, compatible with most current games, Consider the m7 your best budget options! Direct X 7 so don't expect the newest-newest games or future game to run on it, though some will.

XXmb nVidia Quadro2 500 Go (price is unknown but cheaper than the quadro4 700 go) I recomend this card to peaple who use CAD and don't want to spend $320 on the quadro4 700 go: its equivelent to some kind of geforce2, but again as in the work-station quadro series, it has CAD fetures (getting more info)

32mb-16mb nVidia GeForce2 Go ($50 from dell parts??? $25 on ebay) This is another MX series into the go series: It does have a T&L engine but no pixelshader. (32mb only) Anyway, this is not such a great card: it will run about the same amount of games the M7 will. (32mb version only)you probobly have to run the 32mb req. games at 640x480 to get okay performance. It will probobly do you well with those 16mb requireing games though. I recomend this to people who don't realy game or only play old games and want a cheap way out! Stability and reliability isues in some cases! Unsure of DX: no better than dx7

16mb or 32 mb ATI Rage Mobility 128 (ATI M4) ($20 on ebay $40 from dell parts?) This is not what I recommend for gaming on games the require more than 16mb! (i did run cs at 1600x1200 with out lag though on a 16mb m4). Mainly this is in my list for two reason: if your tired of isues with gf2 crashes for people who want stability over features and it will also work with the hitatchi screens i bellieve! Some BIOS isues but (becuase dells drivers sometimes look at your BIOS so be ware 8100/c810, 8200/c840 people) im sure ati's rage drivers or maybe dells as they work with many different unit I4000, I8000, C600, C800: but try ati's first and i doubt you will have problems. No T&L Pixel-Shader unsure of Direct X support.
