I may be spoiled by still running XP but what games push you over 2GB? My machine was briefly around 1.7GB used while playing Assassins Creed and other than that I dont recall every going over 1.5GB.
The above numbers were total memory usage which include a software firewall, IM, and Windows processes.
I'm with you on the 2 years mark. I think anyone running XP will be fine until the next Microsoft OS released.
I also just use total commit although its not fully accurate in terms of how much physical memory the game itself is using. However, along with OS overhead, page file, and super fetch the extra RAM is nice.
Anyways, a few of the games I've physically observed pushing total commit over 3GB are LOTRO, AoC (Closed Beta), Witcher, SupCom, CoH, Titan's Quest, STALKER. I've also read here from user reports that Hellgate: London benefits nicely from more RAM. Pretty much any game that's /largeaddressaware now and going forward. I'm pretty much at 2-2.5GB at least with any game running, but someone running XP might not go over 2GB all else the same due to Vista's higher overhead.
The differences can be subtle in games, the biggest performance benefit imo is much faster loading times for area revisits and less HDD thrashing/throttling. For some games, it can allow you to run higher resolution textures or allocate more RAM for caching textures (AoC and LOTRO both offer this feature).
I'd say the main benefit of moving to Vista now rather than later with Windows 7 would be for DX10. Some may say its not worth it or its too performance expensive, and although the latter may be true, the former certainly is not in games I have seen with DX10. Performance concerns will continually improve as GPUs get faster and the upcoming cards this month should certainly bring DX10 performance in games to a more bearable level.
