RE: AGP Card 4x
Well, nvidia has always been tops as far as drivers go.. Always releasing newer drivers, and are always ontop of any type of bugs where ATI has been known to just ignore certain games if they arent a popular main stream game and just ignore a bug.
The X1950 seems to be well endorsed by tomshardware and does pretty well in most reviews I see, looks like one is $185 after rebate and a bunch in the $200 price range.. If you go for one, make sure your power supply is up to par, I'd think overall depending on what hardware your running Id at least want a 400w psu minumum and id prefer a 500w..
However also I see some other deals on newegg like a 7600GS for $99 after $20 rebate, and a 7800GS for 189 after a $20 rebate, on a BFG brand (factory overclocked) and 5stars with 448 reviews..

The 7800GS scores a bit slower then the x1950, on the tomshardware charts they are close..
Also its possible your cpu couple be a bottleneck and going with a cheaper card for 100-130 might be better, its possible you could spend 200 on a vid card and it not score much faster then a 150 one because your cpu is holding it back, and again your putting this in a 4x slot, you wont get the most out of the card.
I'd go back to thinking about the a card under 150.. This is a 7600GT for 145 after a $30 rebate..

The 7600GT is plenty fast enough to get you through, so is the 7600GS, might wanna save a bit and just grab one of those for about $100 until you can fully upgrade. If your spending $230 for a x1950, it will runfaster at pci-ex 16x then at agp 4x.. You can spend less and get a 7900GT or something like that with a updated system and it'll be faster overall.
as far as video memory goes, most cards with the same chipset and pipelines, will score pretty much identical scores at either 256mb or 512mb.. The more video memory the more it has to do with allowing higher resolutions then speed.. However, you want to make sure if you get a 256mb card its 256-bit and not 128-bit..
