What are you using the system for..?
Hmm, I just realized you had a socket 754..
If you want to get a Socket 939, we can seriously hook you up with a beautiful system.
We can either way, but Socket 939 will be upgradeable alot longer, and I really advise you to go with 939.
As far as video and sound goes..
Your motherboard has an integrated sound card.. although buying a better one is always an option.
Your motherboard does NOT have an integrated video card though.. so you will need one.
My personal reccomendations are a 6600GT if you do moderate gaming but if you want a really good one, head for the 6800GT with 256MB and it'll last you a while. If you want the 6800, check out this card:
Now, your probally saying.. Oh my god.. your killing me with these costs.. It only gets better my friend.
Just kidding.. but if you do alot of multitasking and / or gaming, I'd reccomend 1GB of RAM. I'd reccomend it anyway.. and if you want very good quality RAM, check out Corsair XMS.. Here is the link to that:
I like the cache on your hard drive.. good choice on that.. but, if you get something like a Western Digital Raptor with 10,000RPM, you'll feel the speed.
Its all up to you, your budget, and your own personal use of this computer.
If you want a gaming computer, and you want to crank this baby to the MAX.. we will all help you.
If you want a general system for moderate use, we'll help as well..
Just tell us your needs, and your wish is our command..
Ok, I'm trying to help out how I can, so here we go:
I don't know what your budget is, so I'm trying to stick close to your original price.
Its an MSI motherboard, with enough ports to it, and its similar to what you had (as far as price and everything) but has Socket 939.
A AMD 64 3000+ with a Venice core.. also Socket 939 to ensure compatibility.
Now, if you tell us your budget, and you want to get a top end system, we can hook this baby up. But right now, this is your Socket 939 solution.. I think.
