You oughtta be set then

You can probably even try out the demo on your current rig, always nice to get a feel for it first. But yeah, gut the HP and save mobo/processor upgrades for a later date (I've been holding off for about 2 years). I don't have any experience with ATI cards (I've been a Geforce junkie since day one) but it should run flawlessly on your rig. While my processor isn't strong (2.5ishGhz single core) I think my 9800GT carries the extra weight without breaking a sweat.
Hope come Thursday you're able to get into it
