Upgrading, suggestions plz

[Sakon]

Upgrading a few parts to my PC...was considering just junking my old one and getting a new pc, but decided to keep my old case. Figured I'd ask on here if anyone can forsee a problem, since I'm not the best at judging PC hardware.

Mobo: Asus M2N-SLI Motherboard CPU Bundle - AMD Athlon 64 X2 6400+ Processor 3.20GHz

Ram: 2xPatriot Signature 1024MB PC5400 DDR2 667MHz Memory

Power Supply: Aspire 600W DarkSide Alum Black PSU - Blue Sleeves

Vid Card: NVIDIA GeForce 7300 GT (already have)

Hard drive: Seagate Barracuda 7200 rpm 250gig (already have)

or would it be just better to get a gaming PC already built and ready to go?

build your own, its always the best way to go.

I would get an intel setup, what would be your budget?

Eh, budget is gonna be a paycheck by paycheck, mobo/ram being the first to upgrade. Basically i wanna get mobo/ram/powersupply for under 400, looked up these specific parts off tigerdirect came out to 350ish. The vid card does need an upgrade, but for the time being the rest of my old pc (built it bout 6 years ago) is far far worse off than the vid card, which got upgraded a while back but is due for retirement again.lol
