afternoon all!, well it certainly has been a damn long time since ive last been here! probably about a year and a bit ago, i decided to deviate from the world of overclocking, desktop pcs and insane modding and just go for a nice easy desktop replacement laptop.. well.... that time has come where i just miss the tinkering, the tweaking and well the sheer performance and fun of a custom rig. so back again and armed with £1500 to spend *case excluded, i allready got one* i have specced up myself what i think is a pretty good rig. though after showing it to people i know they have pointed out a few things i might want to consider, and well i thought id come ask the OCUK PROS ;-) ive been out of the picture for a while so am probably a bit rusty, so just wana play it safe, so hope yall can help!! heres the rig im looking to get: CP-148-AM AMD Opteron UP 170 Dual Core San Diego 2.0GHz 2MB Cache (Socket 939) - Retail (CP-148-AM) £249.95 £249.95 MB-018-DF DFI LanParty NF4 SLI-DR EXPERT (Socket 939) PCI-Express Motherboard (MB-018-DF) £109.95 £109.95 MY-060-OC OCZ 2GB (2 x 1GB) PC4000 Dual Channel Gold GX XTC Series EL-DDR CAS3 (OCZ5002048ELGEGXT-K) (MY-060-OC) £144.95 £144.95 GX-112-SP Sapphire ATI Radeon X1900 XT 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (GX-112-SP) £214.95 £214.95 HD-087-WD Western Digital Raptor 74GB WD740ADFD 10,000RPM SATA 16MB Cache - OEM (HD-087-WD) £103.95 £103.95 CD-041-PO Pioneer DVR-111BK 16x16 DVD±RW Dual Layer ReWriter - (Black) OEM (CD-041-PO) £22.95 £22.95 CB-000-WD Western Digital Secure Connect Serial ATA Cable (CB-000-WD) £4.95 £4.95 CA-005-HP Hiper HPU-4K580-MK Type R 580W Modular ATX2.2 PSU - Black UV (CA-005-HP) £54.95 £54.95 FG-024-AK Akasa AK-183-L2B Ultra Quiet 120mm Fan - 3 pin (FG-024-AK) £9.95 £19.90 AC-000-AC Arctic Silver 5 Thermal Compound (3.5g) (AC-000-AC) £5.95 £5.95 HS-017-TR ThermalRight XP-120 (Socket 754/939/478) Heatsink (HS-017-TR) £26.95 £26.95 GX-100-AS Asus Ageia PhysX Accelerator - Retail (GX-100-AS) £169.95 £169.95 MO-012-AC Acer AL1916WS 19" Widescreen LCD Monitor - Black/Silver (MO-012-AC) £149.95 £149.95 Subtotal £1,279.30 VAT £223.88 Total £1,503.18 now im not too bothered about the res of the tft, 1280x1024 and 1440x900 is cool with me i think *THOUGH SCRAPPING THE PHYS-X AND GETTING A HIGHER RES MONITOR MIGHT WORK?* the phys x is cool and i just wanna try cell factor lol and i most probably wont be looking to go x-fire or sli at all so that dosent bother me much either. BUT! THE PROBLEMS THAT SOME OF MY MATES HAVE MENTIONED ARE AS FOLLOWS: 1: someone told me that with a dfi motherboard, the most compatible ram for overclocking is "OCZ" thats why i looked at the pc4000 ocz gold, but to be honest im rather tempted by the "G.SKILL" pc4000 ram as i heard good things about it and well... its cheaper lol 2: the motherboard is an nforce 4 chipset but the card i want is an ati branded card, will there be any performance hit between using these 2 cross branded cards?, i heard so much good stuff about the dfi expert and well its cheaper than the cross fire version too, would these be ok together? 3: well i intend to clock the nuts out of the opteron so would this air cooled combo i chose work well? or do you think it would be better scrapping the phys-x adapter and going water cooled? HOPE YOU ALL CAN HELP! ID REALLY APPRECIATE IT IF YOU COULD! MAYBEE IF YOU THINK MY RIG IS A BAD COMBO THEN YOU COULD SUGGEST A BETTER RIG FOR 1500? *MY ONLY 2 POINTS ARE, I ALLREADY HAVE THE CASE AND I WOULDNT GO P4.* THANKS ALL!!! AND GOOD TO BE BACK!!
