I am wanting to upgrade my graphics card on my GATEWAY E4100. I can't find out which AGP graphics card is compatible. I'm LOOKING for a 128 or 256 MB card. Any suggestions what to look for and the cost?I wouldn't bother spending too much on it, AGP is becoming outdated and the cards are far too expensive considered to PCI-E, which your mainboard is not capable of supporting. If you do buy an AGP card, buy one that doesn't cost more than 100~120 dollars or so otherwise you'll end up with a card that might make the rest of your system a bottleneck for performance

MB RAM doesn't mean a lot. It's the processor core and RAM speed on the VIDEOCARD that makes the biggest difference. Plus the amount of pixel pipelines. In any case; the higher, the better.

What games do you plan on playing?Nothing too graphics intensive. I was looking more for a mid level card that could handle some games and Windows VISTA when it comes out.I wouldn't bother buying Windows Vista for your current PC, when Vista comes out it will be cheaper to buy a new computer that comes with Vista (OEM) than it will be to purchase the OS in its retail form.

Besides, I don't think they're bringing out any Vista-ready AGP cards anymore, like I said, the technology is too outdated. It is now PCI-Express that is taking the lead. This doesn't mean that you can't install Vista on your current machine, though.

What kind of videocard is currently installed?Here are the relevant specs on my computer:
Intel Extreme Graphics 2 controller
Universal 0.8 V / 1.5 V AGP 3.0 connector supporting 1X, 4X, and 8X AGP cards or an ADD cardAny new videocard would most likely make a vast improvement in the 128-256MB range.How much do you want to spend? It can very from £20 to £200+. Have a look at 6600GT for a starting point and GO up or down from there.
