I am debating whether to pre-order Sins of a Solar empire. The only thing that is holding me back is my graphics card: the intel x3100. Yes, i KNOW this is not a gaming card, but its the first intel card with hardware shaders and it can play plenty of games. My processor is the T7300, and I have 2 gigs of ram. Using WinXP. Laptop, so I cannot upgrade my card

Here is some examples of the x3100's performance:
In 3dmark05: 700 points with Hardware shaders on, and 925 points in software emulation mode. Yes, many games will run better in SW mode. However, the games that run better in Software mode often have more slowdown when there is a lot of stuff on the screen.
Unreal 2004: with most of the options turned up in 1024x768, steady 35-40 fps.
Galciv2: very playable. When first starting a game 50+ fps. However, when there is a ton of stuff on screen, it can drop. Late game with dozens of starbases/ships on screen, if zoomed all the way out 17fps, if zoomed in the frame rate goes all the way up to 50fps again.
Civ4: Depends on the zoom level, 25fps zoomed all the way in, but only 12 zoomed out. Depends a bit on how many trees/units/structures are on the screen. And late game, its pretty unplayable.
Guild wars: Frame rate can be all over the place. Options turned very low. In towns with literally Dozens of characters on screen, 15fps. In low populated places, 30+fps. Hard to guess an average for this game.
Rome Total War: 25 fps average unless there are a lot of units/buildings in view, then its about 17fps. 1024x768, graphics set to medium (doesnt seem to make a difference if set to low).
Supreme Commander: Unplayable. In a skirmish game, zoomed in or out, about 10fps. In the first battle sequence for campaign mode about 5 fps.
So, do I take a risk with Sins? Has anyone tried it with the x3100? I've read that many of the special effects haven't even been implemented yet. How will the effects affect the performance? Lastly, how large can the battles get and is there a huge performance hit during the battles?
