How much better will this be?

[fatlaxg30]

My roomate is interested in getting a better computer. He will only use it for email, play music, internet. He currently has:
Dell Optiplex GX400
P4 1.4 GHz
128MB ram
GeForce 2 32mb


How much better would this setup be (keep in mind he wants to keep it cheap since he wont use it for very much, mainly wants a faster computer):
Sempron 64 2800
Epox 8KDA3J
Asus GeForce MX4000 (No gaming)
Antec SLK3000
Fortron AX400 400w PSU
512mb Corsair ValueSelect ram

All this is only $338 shipped at the egg
Any suggestions or ideas of how much better this would be would be appreciated. Thanks

in my opinion, if thats all ur friend do, his old rig will be fine just for that job

Just go with a faster processor and forget about overclocking. Not sure if he was needing a new (bigger) hard drive as well, or some type of ROM, but I put them in there:

COOLER MASTER Centurion 541 w/ 380w PSU - $70

GIGABYTE GA-K8N51GMF-9 - $80

AMD A64 3000+ Venice - Retail - $146

Corsair ValueSelect 512MB (2x256MB) - $41

Maxtor 6L200S0 200GB - $83

NEC 3540a 16x DVD+/-RW - $40

Total = $460

For about $100 more he can get a lot more future-proofed system with an optional DVD burner and 200gb of storage space for music/movies. The mobo has an integrated GeForce6 series chip, so he can even play most last generation games occasionally.
