Help Upgrading old build

[DonMakeVeli]

Well I built this comp about 1.5 years ago and it's been good to me but now its starting to run sluggish. I'm wondering what i could do to it so it runs everything quickly.

Here's the old build:
AMD Athlon 64 3000+, 512KB L2 Cache, Socket 939 64-bit Processor
Thermaltake VA3000 Dream Tower Black VA3000BWA ATX Case with Transparent X type side panel window
Silent TT-550SS Power Supply
DFI "LANPARTY UT nF4 Ultra-D" NVIDIA nForce4 Ultra Chipset Motherboard For AMD Socket 939 CPU
EVGA nVIDIA GeForce 6600GT Video Card, 128MB GDDR3, 128-Bit, DVI/TV-Out, PCI-Express, Model "128-P2-N368-TX"
Kingmax SuperRAM Series Dual Channel Kit 184-Pin 1GB(512MBx2) DDR PC-3200, Model MPXD42D-2
Nec dvd/cd rw drive

What do you guys think i could do to bring it more up to date?

What hard drive(s) are you running? Are they getting full? I have a similar setup in my nephew's PC. His didn't really start slowing down until the hard drive was busting at the seams.

1. You could upgrade the processor to a X2 3800
2. You could/should upgrade that psu to a quality unit.
3. Perhaps a upgrade to a 7600GT? (New video card)
4. Add another Gig of ram.

LoL, well i got an 120gb & 80 gb in the tower and another 80 gig external hd. They are pretty filled up(about 10 gbs total left).

The thing is that i have TONS of stuff i cant get rid of that i need to save.

Mr.Ferrari, Which x2 3800 is better? I see a "windsor" and a "manchester" on newegg.
Also, what psu do you suggest then?
I dont really do too many graphics intensive stuff, so not so sure about upgrading vid card.
Yea, i kno i should get more ram(the current ones are pretty cheap), but what do you suggest? Which brand/type is good with the x2 core?

[Mr.Ferrari]

1. You need the Manchester, the windsor is for Socket AM2.

2. Enhance 400W or Enhance 500W<----ONLY get 500W if you need to future proof for anything except a highpowered dual card configuration. You will be fine with the 400W.

3. Oh ok, in that case your current card is just fine.

4. You need DDR 400. Get something of quality from Corsair or G.Skill, 2x512mb sticks.

Ok, Thanks for the tips.

Which of the g.skill mem do you recommend??

Don't bother spending money on any upgrades except bigger hard drives. Full drives is the source of your issues. 320gb SATA's are pretty cheap now. Do that *before* thinking of any other upgrades.
