Need help choosing parts 4 new rig

Hey all,Need some help choosing which motherboard and brand/amount of RAM I should go with for my new build.My budget is around the $1,100 mark.So far, I'd chosen to SLI 2 Nvidia GeForce 8800GT's. I can get them for about $180 each.Also, I was thinking. What is better... buy a Intel Core 2 Duo E8400 for $211 and overclock it OR future-proof and get a Intel Core 2 Quad Q9550 for $399 (OR Intel Core 2 Quad Q9450 $363).So I ask, I'm looking for a motherboard capable of running SLI, handling 4GB RAM (what type? DDR3?) and has enough bells and whistles to last me a very long time.All help is greatly appreciated.Need help choosing parts 4 new rig

You'r wish as being listen tell us where u live. so i can build from Country you are. il build it over gamespot community approve free to be changed by any other who as better deal then me tough i'm really decent into picking hardware for this year there thousand solution only few that are good 180$ each 8800GT is rip off for sli performances

you can get better build rig of video card for same value : 400$ : when your combine 180x2+tax. you could get a 280GTX that is better if you nvidia fan or 4870 1GB . or add 150$ more of ur current video card build
for 4870x2 but that would over-budget and restrain you to wait a month or Two Before you have enough money to do so it what i did suggest several people on gamespot to wait and get better piece when it does worth it tough but we must start to think of a rig

So If you'r there you said 1200$ ? let See. For cpu : motherboard : ram : hard Drive ? does ur is SATA II ? how much GB ?
OS : we may need a Vista because ur pc is probabely not a XP OEM (Xp that isn't from Pre-buidl pc) but the clean software
a Real XP can be changed to countless pc but it may require telephoen toll-free and speak to the machine
and enter the digit to switch it what i ad to do when i switched hardware from : my old amd athelon 4600x2 to E8600

• we could get maybe
• Intel E8400 / E8500 165-200$
• X48 if ATI / Nforce 790i ftw EVGA for motherboard 200-350$
• DDR2 / DDR3 Depend of motherboard Solution would recommand DDR2 For Economy
• PSU from 750wats to 1K+ WATS engine 120-240$
• After market cooling if overclockign from 40-59.99
• case from 87$-200$
• hard Drive if not sata or can't be reused 75-85$ : 500GB / 640GB
• OS 125$ for Home premium 64 Bits
• video card will variate from 300$-550$ build as we can strech the more
  
  I do Alway build pc like if it was my pc sorta it as to be good :P
  unless you say this pc is not for gaming but heavy station working then id just asy Biggest cpu you can / cheapest motherboard / DDR2 in huge quantity or someting like that. if you aim good hardcore gaming il try to make it so you can enjoy it

Thanks for the reply. I'm from Australia btw. The rig is all for gaming, I barely use any heavy applications. For hard drive, SATA is fine (sorry, I don't know the difference between SATA and SATA II). I'm looking at 500GB space. OS won't be a problem, I have an XP OEM, but it's only 32-bit. Can you really see the difference between 32 and 64?With the CPU, I was wondering if I should grab a E8400 for $211.00 that can be safely overclocked to 4.23GHz. But I was still unsure whether I should just get a very good quad and leave it at that.Motherboards I have no idea about to be honest. Not my area to say the least. But for an Nvidia 790i FTW I'm looking at $415.00 and the X48 ranges from $252 to $450 depending on brand.With graphics.. I'm getting prices of $725.00 for the 4870x2. Compared to $180.00 for an 8800GT. So, what do you think now?
