No, changed the spec to quad core, 2600xt, 2GB Ram and a raid 0 configuration. If I had put more ram in it would of been a 5.9 I think.

I played unreal tournament 3 beta at full setting in 1280x768(max mon res) whilst encoding a file to 720pHD

Some difference in the performance compared to the old system and its definately worth the money to go quad core.
