Best current WinXP game?

[Karlos]

A few I've played recently on the same gfx card (albeit under Vista/DX10) and enjoyed

RPG:
Fallout 3
Mass Effect

FPS:
Crysis / Crysis Warhead (engine now supports high res DX9 and so works fine on XP)
Call Of Duty 4
Orange Box (HL2, HL2 episodes 1&2, Portal and Team Fortress)
Unreal Tournament 3

RTS:
C&C3 Tiberium Wars / Kane's Wrath - though neither need anything like the horsepower

You really should try Crysis if you want a real hardware-pushing (or even punishing) game. You really won't see anything quite like it for a while now as Crytek released it at a time when no hardware could do it justice and made a loss. Now all the games producers are seemingly settling for the safe-bet hardware at the moment.

Your GTX260 will allow you to play it with all details set to very high (it certainly does on mine). It really is visually spectacular.

Steam can be a PITA but it's worth it given the quality of the HL2 universe.

You do tend to find a lot of good deals on there too.
