Setting up new build...need advice

[Arkan]

Ok, i'm putting together a computer for myself. Last time I did this was in 2003 so, a lot has changed since.

New build:
- Intel Xeon X3440 CPU
- ASUS P7P55D LGA 1156 Intel P55 ATX Intel Motherboard
- CORSAIR XMS3 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
- XFX HD-587A-ZNF9 Radeon HD 5870 1GB PCI-E Video Card
- Plextor DVD/CD Writer LightScribe Support
- Corsair 750TX 750W PSU
- NZXT Apollo Black SECC Steel Chassis ATX Mid Tower
- SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM Internal Hard Drive
- OCZ Vertex Series OCZSSD2-1VTX30GXXX 2.5" 30GB SATA II MLC SSD
- Windows 7 Home Premium 64bit OEM

I had planed to use the 30GB SSD as a storage device for music and word files and the Samsung HD for the O/S and games. I realize the SSD is rather small at 30GB (it was cheap storage) but, i'm now thinking of tinkering with the use of SSD and having it as my main O/S device and have all the games and such loaded on the Samsung. I can always get a larger capacity SSD in the future.

I guess my question is: Are SSD's the "future"?...whereas it'll likely replace disc storage drives such as the Samsung, WD....etc? How are gaming benchmarks compare between the two?

How would you recommend me setting up this computer? Parts should be here by weeks end.
