Need help

Currently i have a pentium 4 and a pretty cheap motherboard. Im saving for the Asus A8n32 Sli board, Amd Athlon 3800+ and for a good Pci-e graphic card, but as my computer is soo crappy right now and i dont have a graphic card in my computer yet i need to upgrade it but the problem is i dont have the money. I have an agp slot in here but i think if i buy an agp card it will be a waste of money as i will change my board in around 3-4 months and besides i want to get a PCI-e card. So i saw this budget motherboard and graphic card and i want to know if you guys think i should get it ... I want to get these hardwares and tell me if they are any good or if im just wasting my money :

Amd athlon 64 3400+
Connect 3D X1300 Pro PCI-e card
MSI K8NGM-V Motherboard

Am i wasting money ? Or should i go for it considering right now i have a P4 2.4 ghz with no graphic card. Or should i just save money and get the SLI Mobo ?

And one more question, Is there any motherboard which supports both dual core and single core amd processors and has 2 PCI-e slots ? I was wondering if i could get the hardware mentioned above and then get the mobo which supports dual core and then upgrade one by one.

All those would be pretty good, actually. But there really isn't a huge difference between the 3400 and a P4 2.4, to be honest wit hyou. I mean, I'd just buy a chep AGP card for the current computer and then not buy a new computer until Vista is out. Sure the Athlon 64 is "64-bit" but most people still use the 32-bit Windows with their 64-bit CPU's, so there's no point in having spent the money on a 64-bit CPU (trust me, I have 2 of'em, both running 32-Bit OS's, even though I'd RATHER run XP x64, it's still kinda buggy, and nothing really takes advantage of it, so there's no point).

Buy a cheap AGP card for you computer, and wait a few months. Trust me - the difference in having a good graphics accelerator right now will be a big enough difference to tide you over until February or March, and by then you'll have a bigger stash set aside.

NuAngel is correct. Right now isn't the time to buy a new machine.

I also wouldn't go for the socket 939 architecture when you do buy anyway. Your best bet is to go with the new AM2. In a few months you should see great advancements and probably another processor war.
