how's it gonna run?

Before:
AMD Athlon 64 3500+ Cpu
1.5 Gb Corsair RAM
ECS K8T890-A Motherboard
Geforce FX5200
got about 20 fps steadily on mainly low graphics...
and now instead of the FX5200 video card, i just bought an 8800GTS
will it finally look nice and play great? or do i need to buy more.

i like what i see here
