New computer rig- thoughts?

[Adelpha]

Hi, just wondered what you thought of this as a gaming rig?

Processor - Intel Core 2 DUO E6400 "LGA775 Allendale" 2.13GHz (1066FSB)

Mobo - Asus P5B Deluxe (Socket 775) PCI-Express DDR2 Motherboard

Gfx Card - EVGA GeForce 7900 GS 256MB GDDR3 HDTV/Dual DVI (PCI-Express)

Ram - Crucial 2GB (2x1GB) DDR2 PC2-4200C4 Dual Channel Kit

Im also looking for a good hard drive and case so any suggestions?

Budget is £700

Thanks!
