Hmmm, this doesnt help me. I have conquered FO3, and all the games in the Orange Box. I cant play online, so the only game someone has listed that
I can play in windowed mode is CIV 4. The games can be older too, I tried Company of Heroes, and Heroes of Might and Magic. Plus I tried Red Alert.
These games do not run in windowed mode, so saying lots do is not true. I have googled for a list but cant find one

Ok, I like FPS, RTS, RPG, MMO, pretty much ALL games except Simulators. And as for my requirements, I can run anything out now and in the past.
I didnt think the list would be that big since there arent that many.

Windows XP Pro.

Core DUO 3.2 OC @ 3.8Ghz
ATI Radeon 4870
4GB Ram

I need to run a game in windowed mode so I can work and play at same time, I know that I can lay WOW this way. And I think Diablo 1 and 2. And Sims will run in windowed mode.

Does anybody know of any others that will run this way.

I was playing Fallout 3 this morning, and my PC shut down. I rebooted, started playing it again and it shut down. I recently bought a new Video Card 2 weeks ago Radeon 4870. So this thing wants 500W minimum. My PSU is 500W. I have had no problem for about 2 weeks and today I notice a high pitch whine coming from power supply. It gets louder if I start running a graphics intensive game like Fallout 3 or 3D Mark. It is fine right now, but as soon as I run a game, it shuts down the PC. At first I thought it was the CPU, but I dont think they make noise like this. So I think it must be the PSU or vid card.

What do you think, do PSU's make noise like this when pushed?

I purchased a new 4870 yesterday, and I it recommends a 500W power supply. I currently have 550W.

Currently I am running 3 harddrives, two DVD writers, 2 case fans, XFI soundcard, and after market fan on CPU.

Will 550W still be enough?
