Memory and CF PSU questions

I am looking at putting together a new PC, and I am not quite sure on a few items in regards to my build.

The core components I am looking at so far, are as follows:

Intel Core 2 Quad Q9550
Gigabyte GA-X48-DQ6 LGA775 DDR2-1200
Sapphire ATI Radeon HD4870 1GB

The place where I am going to buy my PC from has access to Corsair, Crucial, G.Skill, Kingston, Mushkin, OCZ, and Patriot DDR2-1066 memory.
The question is, which should I go for?

http://www.computerlounge.co.nz/components/componentlist.asp?parttypeid=168&t=1
* Corsair TWIN2X4096-8500C5D 2x2GB XMS2 Dominator DDR2 Performance Memory
* G.Skill 4GB kit (2GB x 2) DDR2-1066 (PC-8500) CL5-5-5-15
* Mushkin Ascent eXtreme Performance XP2-8500 2x2GB 1066MHz 5-5-5-15 Dual Channel kit
* Patriot Extreme Performance Viper Series DDR2 4GB (2 x 2GB) PC2-8500 Enhanced Latency Dual Channel Kit 5-5-5-15

Also, I've seen review of the Corsair 1000W modular PSU. Will this have the correct connections for running ATI 4870 CF? I am going to get one card to start with, but want to add a second card later on.

All those ram kits are more or less the same, just go with the cheapest. 1000W is way over the top, something in the ~600W range would be around 50% load most of the time with a system like that

At a glance I agree with the above.

Q9550 is around 90W under load, up to 140W overclocked. 4870 1GB is around 130W under load. Two of them under crossfire draw a little less together than when they're alone, coming in at 255W. The rest of your system will generally draw around 30-50W.

So with that CPU overclocked you'd be looking around the 450W mark under full load. So even the Corsair TX-750 would be looking at around the 63% load mark.

The Corsair 1000W would be less than 50%, which is quite nice. Plus if you got the HD4870X2 you'd be running around the 60% load mark, which is a nice option.

If you're sure you're not getting the HD4870X2 then the Silverstone OP850 would likely be my suggestion.

Well depending on whether or not this system will be overclocked I wouldn't see this system needing more then 750W, seeing how CrossFire will later be in the mix. So in the case of it not being overclocked, then get a Zalman ZM750-HP. And if your going to overclock then you'd be looking at getting the Zalman ZM850-HP. Both are very efficient, and quiet power supplies.

The system that I am pondering over is like this:

Intel Q9550
Gigabyte GA-X48-DQ6
Corsair TWIN2X4096-8500C5D 2x2GB XMS2 Dominator
Sapphire HD4870 1GB (x2 eventually)
SAMSUNG F1 640GB x 2 in RAID0
Thermalright Ultra-120 Extreme + 120mm fan
Silverstone TJ10 + 120mm fans
Corsair 1000W HX modular PSU (specs show it has the correct power connectors for the 4870)

+ Vista 64-bit OEM (possible vLite it first) and whichever 64-bit linux I get around to installing :)

This will be running a Dell 2408WFP monitor, playing WAR and occasional forays into CoD4 and other FPS games.

I was thinking about overclocking the CPU, with a Noctua or Sycthe fan attached. Any recommendations for either brand?

Is there any difference between TJ09 and TJ10 apart from the door?

My current system is a SFF box, and it's too small, and I want to go back to a decent sized tower. The TJ10 looks like my old Coolermaster ATC-110 case, but with better hinges on the door (can remove the door).

I like the idea of the 120mm case fans, as having 6 80mm fans plus everything else going was too noisy. The current SFF has no sound protection, and the old Raptor 74GB is LOUD. I see people mention Samsung are rather quiet.

You wouldn't have to get a 1000w PSU mate, just get a 850W seeing how your going to be overclocking, and then instead of the 4870, get a 4870X2 with the money saved on the power supply. Also save some dough on the RAM, get some cheaper stuff. Then you should be crankin'

Also if you decide you will get the 4870X2.. also think about if you would want to add another card to that later. Because another 4870 CrossFired on that would haul arse... and drain power like no tomorrow.

OK, so I have swapped Corsair PSU with Zalman 850W, which is a bit cheaper.

Intel Q9550
Gigabyte GA-X48-DQ6
Corsair TWIN2X4096-8500C5D 2x2GB XMS2 Dominator
Sapphire HD4870 1GB (x2 eventually)
SAMSUNG F1 640GB x 2 in RAID0
Thermalright Ultra-120 Extreme + Scythe 120mm S-FLEX Fan, 1200 RPM
Silverstone TJ10 + Scythe 120mm S-FLEX Fans
Zalman ZM850-HP 850W PSU
