<EDIT: Ignore the orange text section. You don't want SLI, it won't benefit your needs at all. (I was posting this while you were replying above - given the new info, you don't want SLI.)>
<font color=orange>Ok, first off, SLI video cards and motherboards are supposed to be out VERY soon. That by itself will give you twice the video card performance that Dell would have given you. But it's not quite available yet. If it were, you'd get this motherboard and graphics card:
$300.00 <A HREF="http://usa.asus.com/products/mb/socket939/a8nsli-d/overview.htm" target="_new">ASUS A8N-SLI DELUXE NFORCE4 MOTHERBOARD</A>
$495.00 XFX Geforce 6800 GT PCI-Express
$495.00 XFX Geforce 6800 GT PCI-Express
But I think SLI and PCI Express aren't quite worth it right now. It's always dangerous to jump on a new technology, especially a new bus type, the minute it comes out. It ends up having bugs in it, and you get to be one of the people who has to put up with the problems until they get fixed. Much nicer to watch other people hammer those out and then get the new technology when it's stable and well-supported.</font color=orange>
So if you <i>don't</i> wait for PCI Express parts to come out in the next several weeks, and if the thing you want this computer for is running games, then this is what you want:
$400.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=14-130-208&depa=0" target="_new">EVGA Geforce 6800 GT with Doom3 Bundle</A> (easily overclocks to Ultra speeds with no special modifications needed.)
$140.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=13-130-468&depa=0" target="_new">MSI K8N Neo2 Platinum NForce3 Ultra motherboard</A>
$295.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-498&depa=1" target="_new">AMD Athlon 64 3500+ Winchester, Retail Box</A>
(which you can see <A HREF="http://www6.tomshardware.com/cpu/20041115/pentium4_570-12.html#directx_9" target="_new">Here</A> is faster than the P4 570 in games.
$190.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=20-141-144&depa=1" target="_new">1GB Dual Channel DDR PC3500 memory</A> with room for overclocking. You won't need more than a gigabyte, but if you want you can get <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=20-141-182&depa=1" target="_new">this</A> instead. (but there's no room for overclocking.)
$65.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=27-106-962&depa=1" target="_new">Lite-On 16x Double Layer CD/DVD +/- R/RW Drive, Black</A>
$7.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=21-103-203&depa=1" target="_new">Samsung Black Floppy Drive</A> Hey, might need it for SATA drivers.
$100.00 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=11-129-127&depa=1" target="_new">Antec Sonata quiet computer case w/ 380W power supply</A> I'm pretty sure 380W is enough for an Athlon64 and a 6800 GT. Might want to ask on the forum to be sure. If it's not you've still saved enough to buy any replacement power supply you want.
$354 (2x $177) <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=22-144-160&depa=1" target="_new">WD Raptor 74GB 10,000rpm hard drive, x2 RAID-0</A> In a gaming machine you'll be hard pressed to use more than this, but if you do you can buy another drive later.
$400 to $1000 Go to Best Buy or someplace and find a monitor that you really like the look of. (you really can't shop for those online.)
$112 <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=29-102-171&depa=1" target="_new">Sound Blaster Audigy2 ZS Gamer Edition</A> with a bunch of games included.
$30 or so for a keyboard, maybe like <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=23-184-003&depa=1" target="_new">This One</A> that has a backlight for the keys for playing in the dark.
$30 or so for a mouse, maybe like <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=26-105-148&depa=1" target="_new">This One</A>. I like the side buttons, great for extra functions in games like zoom, run, or grenades.
EDIT: forgot the OS. Knew I left something out. Modified final prices.
$100 for <A HREF="http://www.newegg.com/app/ViewProductDesc.asp?description=37-102-151&depa=0" target="_new">Windows XP Home</A>
Did I miss anything? I think that's all you need to have a great system. You could bump up to a 6800 Ultra for another $150 or so, if you don't want to bother with overclocking to match or exceed the performance of the Radeon X800 XT.
The total is now $2223 to $2823 depending what monitor you get, or maybe $2373 to $2973 if you get a 6800 Ultra instead of a 6800 GT. Shipping might cost another $40 or so due to the case. It also comes with Doom3, Star Wars: Jedi Academy, Splinter Cell, Halo, Rainbow Six 3, and Tomb Raider: Angel Of Darkness. You could even <A HREF="http://www.mwave.com/mwave/ProdMOTHERBOARDBUNDLE-MSI.hmx?updepts=BUNDLE.hmx&DNAME=<b>MB+BUNDLE+w/+CPU</b>&back=ProdMOTHERBOARDBUNDLE-MSI.hmx?" target="_new">buy the motherboard, cpu, and ram together as a bundle</A> at mwave.com and have them assemble and test them for you before shipping.
See why we like building computers?
EDIT: also this system will be more towards the gaming end than you will want, but it is comparable to the Dell system.
