Okay, I need help with deciding whether or not I should build a gaming PC or just buy it from HP with good $500 discount. Let me list different parts of my build vs HP build so all you people can help me on which one is better. My build: CPU: Intel Core i7 Extreme 980x, 3.33GHz (Six Core) 12000K CPU Fan: Intel Socket 1366 CPU fan Motherboard: ASUS Rampage III Extreme X58, DDR3, SLI & Cross Fire,SATA3, GB LAN, USB 3.0,iEEE RAM: 12GB (3x4GB) PC3 10600 DDR3 1333 Triple Channel Graphic Card: ATI Radeon HD 5970 2GB PCI Express 16x dual head DVI, HDMI Hard Drive: 1000.0GB Western Digital Green SATA2 UDMA 300 32m cache DVD: LG 22x DVD Recorder Dual Layer +R/RW -R/RW Case: Antec Twelve Hundred Black Case, Full Tower, Side Window, front USB & iEEE Power Supply: Antec TruePower Quattro 1000w Extra Quiet ATX Power Supply SLI & X-fire ready This come out about $3400 with shipping fees and taxes after I use price check with Tigerdirect.com and Newegg.com HP build: CPU: Intel Core i7 Extreme 980x, 3.33GHz (Six Core) 12000K CPU Fan: Intel Socket 1366 CPU fan Motherboard: Pegatron IPMTB-TK http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01901210&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us%E2%8C%A9=en&product=4#N825 RAM: 24GB DDR3-1066MHz SDRAM [6 DIMMs] Graphic Card: 1.8GB NVIDIA Geforce GTX 260 [2 DVI, HDMI and VGA adapters] Hard Drive: FREE UPGRADE! 1.5TB 7200 rpm SATA 3Gb/s hard drive from 1TB DVD: Blu-ray player & Lightscribe SuperMulti DVD burner Network card: Wireless-N LAN card Media Card: 15-in-1 memory card reader, 1 USB, 1394, audio Case: HP case with dimension of 16.85"(L) x 7.05"(W) x 15.79"(H) Power Supply: 460 watts OP: Genuine Windows 7 Professional 64-bit This comes out around $3100 after taxes (free shipping). $2,902.99 before taxes (initial price $3,402.99 before $500 discount) As you can see HP build is cheaper than mine even though I have concerns in a few areas. First of all, their Power Supply is only at 460 watts so if I want to upgrade something in future, it will cost me more with building a new Power Supply. I don't know much about their motherboard so if someone knows about it, please help me explain. Another thing about is I can't get much information about their 1.8GB NVIDIA Geforce GTX 260. I know you can only buy 896 MB GTX 260 outside. I talked with HP live chat agent and he said 1.8GB GTX 260 is only made exclusively for HP 390t and you can't buy it outside. Well, beside these few points, I like HP build. I think my build has better motherboard, Graphic card, and power supply. It's more expensive. HP build has better RAM, more hard drive, better media card readers, and cheaper than my build. So which one should I go with? Thanks in advance for help.
As to the power supply, some HP systems use proprietary power supplies, so simply swapping theirs out for a reasonable sized supply (IMHO 750Watts would be minimum for that rig) would be harder.
ATI mutli-card scaling is worthless, honestly you're better off getting 2 GTX480
Nvidia's DX11cards have a near 100% scaling ability unlike ATI who's cards give less then 50%
If you're planning on overclocking then you will have to get rid of the stock cooler
