7800gtx or new Mobo, case and Memory

[Aristotle13]

First off, hello from the new guy. Been reading, decided to join.

I recently got into tweaking my cpu after buying an HP1230n and have been enjoying playing online.

Anyhow, those 3dMark scores sure makes a fella think. And have been considering getting a new gpu and decided on a 7800gt.

then I thought, the real glaring weak link in my system is having an HP proprietary ASUS AmberineM mobo, all being cramp in a miniATX HP box, and my memory is not the lowest latency pieces.

then I started thinking. Would I be better off getting an SLi capable mobo like a DFI LP. And some quality, low latency memory (muskin,corsair xms). That way I can fool around a little with OC'ing my AMD3700, slap everything I had in my HP in a nice Lian Li box.
And save up my money for this years newer cards when they come out later this year instead of putting all my money on what's soon to be old tech (7800 cards). And just run the 6600gt card for this year?

Here's my set up...

HP a1230n
AMD3700+ Sandiego @2.2
Asus AmberineM mobo skt939
6600gt @560/1200
Audigy ZS
2 gigs Corsair 4x512 ValueRam
200 gig SATA/150 Seagate Cuda
CD/rom & DVD/RW Lightscribe x16 DL
Antec TP2 480w

Again, I'm setting this machine up for gaming.

Or is this money just burning a hole in my pocket?
Input is very much appreciated. Hope I'm not asking too much for my first post.

I think your machine is just fine for games the way it is. If anything all you need to do is replace the video card when the new cards come out. Just buy a 7800GT when the prices fall.

What sucks is the HP is only a 5 weeks old and I paid for a two year warranty when I bought it at Frys. LOL

Guess swapping mobos and case will probably void that. Glad it was only $70 for the warranty, still, hard earned money down the tubes.

I would just get a new video card and forget about the motherboard until you are ready to build an entire new system in a couple of years. 7800 GT should be able to play any game you want unless you are on some kind of 24" screen or something.

A new video card will do wonders. A lot of new games are more GPU bound.

I still have an old Barton 2500+ (although o/c'ed to 3100+), and with an ATI X800 Pro, it performs well in most games.

Get the card as long as the PSU can handle it.
