I can't tell if all these crashes i have are with EB or graphics card problems...

@Iamphet: that's not true for the 'simple' new versions -- i.e. those where it's basically the older version with some design flaws fixed or given some more memory just for the sake of making the thing more competitive price/value wise...

@Dayve I've experienced similar behaviour (not just with RTW with other programs ending for no good reason as well) with a different machine (which I assembled recently, and which will replace the one I posted the specs of earlier). It went away after I updated my Windows Vista (pity you have the by now no longer supported XP) + tried overriding my GFX card settings in the CCC program ATI ships for controlling/configuring its drivers. The funny thing was that the only changes I could make to the settings essentially meant forcibly use high settings for the cases a program wanted to use low settings.

I should note that the card never would run very hot as sits right beside a 900mm (case-side) fan, now it does run a bit more hot. You may want to check if your GPU already runs very hot before you try this, but if you find it runs at odd low temperatures (the 48xx are apparently known as true central heaters) you should try.

EDIT: And now I can replicate the feats of stability of the old machine in the hardware specs thread too.
EDIT2: Driver version 8.530.0.0
