It's much more likely to be DDR2, although nobody mentioned it, and it's not so important since I don't think that system needs the RAM upgraded. nForce 430 is from 2005, so that's a good guide to how old the system actually is. It was a low end system back then, although those days systems didn't need to be overly powerful. These days, it doesn't stand much of a chance in modern gaming.
I believe Rydian is more informed of how well a graphics card update would improve gaming performance, so I won't comment on that. I'd recommend a complete system upgrade (i.e. motherboard, CPU, RAM, graphics and case), but naturally that all depends on the budget available (which I get the impression is quite low in this case).
Vista's initial appalling performance has gained it a lot of hate, mostly due to pre-mature drivers (mostly associated with graphics), but since 2008 it's been able to match XP performance in adequate computers (which generally means ones that aren't low-end systems from over 3 years ago). Now it's a viable OS (perhaps with a little bit too aggressive UAC) for those who don't want to/can't afford Windows 7. Personally, I find W7 much more attractive as an OS - not because of performance, but because the interface is nicer (especially the "snap" functions). It also helps that I got multiple copies of Windows 7 very cheaply.

omg, did you use it? on your main pc? it was terrible
Yes, I used it on everything 4 years old or newer. My main computer handled it just fine. My media laptop was a lil slow to load, but it handled it fine. My tablet laptop is slow (I blame the AMD AthlonII CPU for that) and has a rather low battery life, but I still used it for all my university work away from home. My brother's laptop was a lil slow with it, but it still worked fine. His main PC was built with highest-spec parts, and did a lil song and dance for him when Vista loaded (just to show off how powerful it was). Of all the above, only my tablet laptop still has Windows Vista (the rest are on 7), and that's only because I've tweaked so many of the settings and system files to make it run at a normal speed on it that it half resembles my earlier memories of Linux - only with a pretty interface to work with. As you can tell, Vista was NOT terrible, at least in my experience.
