I would not waste $300+ on a Ti500 right now, the Geforce4 will be here very soon. An ATI Radeon 8500 is a good choice at under $250. No matter what though I think you need to watch your money, it sound's like you want to blow every penny you have, and in terms of hardware it's easy to do it. After upgrading a half dozen times over the past couple years I've learned to buy what is the most reasonable, not necessarily what's the fastest. I wanted the best for my money at the time, and I spent about $1500. Here are the major components:
Gainward Geforce3
Athlon XP 1800+
512MB Crucial PC2100 DDR*
Shuttle AK31A KT266A (a better choice would have been a Soyo K7V Dragon+)
30GB Maxtor 7200rpm (40GB would have been better)
WindowsXP Home
Plextor 12x10x40x
SB Audigy Platinum (wasn't worth the money, the C-Media chip works perfectly fine)
Hitachi 19" CM721F
Antec SX1030
*I purchased 512 at the time because it was too cheap to pass up, paid $72 with shipping.
