my current comp in its incomplete state:
3.2 ghz p4
1Gig ram
Geforce 3 ti 500
onboard sound
2 36 gb 10k rpm raptors in raid 0
two turtle doves
it runs eq2 just fine. i have it on "high performance (almost middle)" with some things set a little higher and it looks great. Eq2 graphics settings are less "what do you want to turn on" and more "how far away do you want things to look good"
is your mobo socket 478 or 3..7.. whatever...? if it's a 478 and supports ht i would say keep it.
as for type of video card i would say get an nvidia 6800 (ultra, non ultra, whatever). Dx9c was just patched in and for right now, those optimizations are nvidia only.
oh and definetly get a sound card. a soundblaster audigy 2 is $99 and will take some load off your processor. tho, even on a onboard, the sound in this game rocks.
as for me, i'm getting an audigy 2 and a 6800 ultra and calling it quits. (which is a technical term for starting on building another computer
)
Edit: oh and more ram... and better speakers.. something thx cerified..oh and one of the new power supplies where you can disconnect any unwanted cables... oh and blacklights.. mmmm blacklights..
