SHould I upgrade my hardware?

[Sik_Inc]

Im fairly amateur to all of this so its a bit overwhelming, granted ive been using reason since it was 1.0, ive just never used it on good equipment. Now im getting pretty serious about this and need to know if im headed in the right direction so this is my setup.
Comp:
amd 64 2800+
Soltek SL-K8T Pro-939 w/ VIA K8T800Pro + VT8327 chipset
512mbGeil Golden Dragon DDR400 2.0 cas
Audigy 2 ZS platinum Pro
Studio:
MXL 660 Condensor mic
Behringer 4 track Eurorack / using phantom power (good?)
M-audio Oxygen 8 midi controller
pair Stanton str8-60's
numark mixer(model escapes me at the moment
planning to get a pari of M-audi BX5's

Software:
Reason 3.0
Recycle 2.1
Cubase SX 3.0
Native instruments Battery 2.0

Any comments or suggestions please lemme know constructive criticism always welcome, and also if you wanna hear what ive been making with this setup drop me a line

it will be wise to not use an audigy, better use some M-audio model with a lot of inputs, so you can also bypass the need for an analog outboard mixer (the 4 track behringer)
