computer advice

now that i have some dough, im thinking about getting a new computer. I'm looking at Dell right now, and what I'm leaning towards is:

Dimension 4600
Pentium® 4 Processor at 2.40GHz with 533MHz front side bus
512MB Dual Channel DDR SDRAM at 333MHz (2x256M)
40GB Ultra ATA/100 Hard Drive (7200 RPM)
17 in (16 in viewable,.27dp) E773c CRT Monitor
128MB DDR GeForce FX 5200 Graphics Card with TV-Out and DVI
cd burner and reg cd drive, keyboard, mouse, winxp, and some microsift sfot2are.

about $800 bucks. What do u guys think? is that too much? I also looked at compaqs, but they seemed like lesser quality. Dell also sells refurbished ones, but cost would almost turn out to be the same.
