also if u know the place where i could find similar spec pcs cheaper pass the link for me. i appreciate it

first question:

what are you planning to use this hi spec system for ?

hi there, i would go for the core i7, more recent tech that rules out fsb by using qpi ( quick path interconnect) solid boards as well intel. The nforce chipsets seem to generate alot of heat compared to intel chipsets. i had to replace both my northbridge and southbridge heatsinks on my Evga 680i because of chipset heat problems. also i wouldnt go for the asus striker 790i because thats when they started to go bad, i had one, failed on me straight away with " cpu init" error, board was duff basically and lots of people reporting the same problem with them series of boards.

Graphics cards i would go for gtx 260s, two or even 3 way sli, pick the cards up for about £180 a piece. them ati radeon 4870 suck up more power than the 260’s.

Motherboard: possible switch to EVGA X58 3X SLI, X58, (Socket 1366) PCI-Express DDR3 Motherboard, don’t know if it has SAS ports like the Asus has but this board is a good overclocker, with reports of the i7 920 going from 2.66 to 3.8 air cooled. http://www.novatech.co.uk/novatech/specpage.html?evg-x58

power supply: i recommend Enermax PSU’s really high quality. http://cgi.ebay.co.uk/Enermax-Galaxy-1000W-EGX1000EWL-ATX2-2-Modular-PSU_W0QQitemZ160317133332QQcmdZViewItemQQptZUK_Computing_PowerSupplies_EH?hash=item160317133332&_trksid=p3286.c0.m14&_trkparms=72%3A1690|66%3A2|65%3A12|39%3A1|240%3A1318

cpu heatsink: thermalright ultra extreme, thats a bad boy heatsink BANDAR288 - Link Login Situs Pesan Makanan Korea Secara Online .

Internet: switch the wireless G card to Wireless N card more future proof.
