So I finally replaced 2 of the final pieces of hardware original to my hewlitt packard pc. Replaced the mother board and the processor.
New Specs are:
EVGA 750i sli ftw
intel e8400 w/ hr-01+ @3.6Ghz
EVGA 8800gt stock
2GB Patriot CL5 DDR2-800Mhz PC2-6400
Antec Truepower Trio 650W PSU
Seagate 250GB hard drive
XP32
all in a CM690
I couldn't be happier at the moment. no issues whatsoever, overclocking the e8400 was a cake walk (this coming from someone who has never overclocked a processor before). Everything went together almost perfectly. Only issues i have now are some very noisy fans which i'll have to deal with soon.
I'm sure the noise will piss off someone in the household enough that they'll get me a fan controller ::) as i've used up the last of me grad gifts.
As a matter of interest the rig, out of the box, stock clocks scored 11,637 in 3dmark06 and after overclocking the cpu scored 12,258 (keeping in mind thats the basic version)
