Right.. after much pondering about which mobo & some helpful comments from you guys.. I've pretty much decided on the Abit A8N Fatality board (though I'm still open to change my mind...) because of it's overclockability, good hexus review and so on.
So anyway heres the full spec of the proposed system:
A64 3000+ (Venice) (£101 Scan), edit: Now consdering the 3700+ (£190)
Abit Fatal1ty AN8 SLi (£121 Scan)
Sapphire X850XT PE PCI-E (£298 Scan)
2x80gig Samsung Spinpoint SATA-II (only SATAII drives I could find that are 80-120gig) in striped RAID. (£42 each Komplet)
edit: to save shipping; 80Gb Hitachi (IBM/HGST) Deskstar 7K80 (£38 each Scan)
Geil (Value 6-3-3-2.5) PC3200 2x512mb (already have this)
430w Tagan EasyCon (not seen much about this, but I know Tagan are a decent PSU brand & the cable management appeals to me). (£55 Scan)
So, what do you think?
Cheers.
