New System, please advise for the last time...

Hi,

I posted a couple of threads and read the various answers. I also read other people's threads and came to the conclusion that for a system that needs to run 2 or 3 virtual machines, it is much more important to get more RAM that buy the latest DDR3 RAM.

Today, I would buy the following system. Could you please tell me what you think? Thinking about future upgrades, do I really need a 750W or a 610/650W?

Please do not look at the budget, since I am not paying for it :-)

- Ultra-120 eXtreme Papst U-Silent - 120 mm
- OCZ Memory 2x 2GB KIT PC2-8000 Platinum-Series XTC, DDR2, CL5-5-5-18, 1000MHz, 240Pin (total 8GB)
- ASUS Maximus Formula, ATX, Intel X38, FSB 1333MHz, Intel S775, 4xDDR2 1333MHz, PCI-E 2.0, C2Q
- Sapphire Radeon HD4870, 512MB DDR5, 750Mhz, ATI Radeon HD4870, PCI-E 2.0, 2xDVI, 2xVGA, AVIVO
- Intel Core 2 Quad Q9450 (2667) Quad Core, Sockel 775, Intel, 2x6MB Cache, 1333MHz FSB
- DVD BluRay BD-6x4x HDR3x +16x8x4x -16x6x4x, SATA Anschluß, LightScribe, Farbe: schwarz, Retail NMS

- PC Power+Cooling NT Silencer 750Watt, ATX2.2, 6x SATA, 8x Molex, Quad Cossfire Ready

Thanks a lot.
Mike

as above, 550W should be fine, but I always recommend 650W minimum to be safe.

Is this a business machine, running RAID and the multiple VMs? Why does it need an HD4870 GPU?
