but can the new version support huge games like san andreas and half life 2?

2 Gigs of RAM is very good for Parallels. But you shouldn't forget that Parallels supports only DirectX 8.1 yet. That means that you will not be able to run all the available games, but only a few. In some time Parallels, of course, will provide better 3D support. But I would use Boot Camp for gaming until it is done.

I'm not sure about San Andreas, but I think that H-L 2 will not work, it is a new game, I assume. I'm not very much into the word of gaming.

Aha! I was not aware of the DirectX-only support! Have they mentioned plans to incorporate OpenGL in the future? I was definitely planning on getting Parallels, but now I'll have to check my most-played games to see if it will really be worth it.

I wouldn't consider H-L 2 a new game. It came out, what, a year ago?

i think 1 and a half, but graphically its huge, and san andreas is like the biggest game ever. but if it ran games like that smoothly i would consider buying it, and while were on the subject of gaming, with the new gaming engine for leopard, maybe games like gta 4 or hl episode 3 will run on mac anyway and the need for having windows just for games will fade away, but seriously imagine how cool gta would be on a mac :)

OpenGL does work, but DirectX is only supported to 8.1, which is pretty old.

Sorry for disinformation, I failed to put it right: Parallels of course supports OpenGL, I meant that it supports DX8.1 and earlier when I saud "only"
Parallels Desktop 3DGraphic support - info from their homepage
Well, as I have said I know almost nothing about the world of games, that's why I don't know when Half Life 2 appeared. But it definitely requires something more than DX 8.1

- as you can see from Parallels site, they say that it supports Half-Life 2

Here's the list of games that, according to Parallels team, will definitely work(they have been thoroughly tested).
The list is said to be frequently updated. Check the link above in one of my posts.

sounds good, has anyone tried any of these more graphical games? do they run smooth like in native windows

I haven't tried anything yet, but they have a demo on their page. I have already posted the link somewhere in this thread, here it is once again: link. There's a video about running games in Parallels - Quake 4 and something else, I don't know.
All this sounds very good, you are right. A great prospect for gamers

so i'm thinking of switching to a mac...
im thinking of using either parallel, but if i wanna play some games would it be better to get 1 or 2 GB of ram? im not a hardcore gamer or anything.

or should i just get boot camp? becuase ive heard that its better for games?

An eternal RAM question...
If you want to have a fast system, take as much RAM as you can afford. For Parallels 2 Gigs will do good.
Parallels supports OpenGL and DX8.1 - if you want to run games that require a higher version of DirectX get Boot Camp, it's free.
If you need to run Windows on your Mac simultaneously with Mac OS (that's a very useful feature I should say), then get Parallels Desktop.
Well, I've summed it all up briefly for you:)
