Logitech Z-4 is a good choice..!

If you can, buy it :)

If you can swap it without cost.. do it..

Look some bench and reviews or comentaries.. the 8800GT its really better than the 2900XT..

Good luck :)

Well.. Im gonna buy a new rig.. Im from Argentina then the price are very diferents :S (Its more expensive on Argentine xD).

In a short time Im gonna post the specification on this forums so you can rate it..

PD: Sorry for my english.. its pretty bad :S

Great list.. It will help me chosing a VGA.

Thanks!
