hi guys

im guilding a new pc with

windows 7 ultimate

intel i7 975 extreme edition
Integrated memory controller enables three channels of DDR3 1066 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. This memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.

Gigabyte GA-EX58-UD4P Motherboard
supports Intel® Core™ i7 Socket 1366

6GB (3 x 2GB) DIMM Kit / DDR3 / 2000MHz / Low Latency / Patriot Extreme Performance Viper Series / PV236G2000LLKB
XMP Ready for Core i7 Processors
Tested and compatible with Intel® X58 Express Chipsets

1. the patriot ep memory is compatible with my mobo and processor but the processor says it takes 1066 memory


2. i want dual sli video cards
which one do you guys think is better

EVGA GeForce GTX 295 1792MB PCI-Express CO-OP Edition Video Card

BFG GTX 285 2GB OC PCI-Express Video Card
 
That's probably a typo; it should be 1600MHz, not 1066MHz. And I would recommend getting the i7 920; the 975 is a waste of cash and is not dramatically faster than the 920 for the far higher price it commands.

You can also do with the cheaper GA-EX58-UD3R instead of the EX58-UD4P IMO.

In addition, I do not think you really need 2000MHz memory; a 1600MHz triple-channel kit would be fine IMO.

Do not bother with using either of those cards (especially two GTX 285s in SLI) unless you have a display capable of 2560x1600, since that's where the full potential of these cards would be realized. I would recommend an HD 5850 for anything upto 1920x1200.

BTW, what PSU will all of this run on?
 
also will this memory work with my processor?

Patriot 4GB DDR3 1600MHz Desktop Memory

Patriot:
FRYS.com #: 6006068
2 x 2GB DDR3 1600MHz Modules
Extreme Performance PC3-12800 (1600MHz)
Low Latency (7-7-7-20)
Equipped with lightweight aluminum heat-dispersing shields

thinking of buying 2 of those
 
I agree with Rage on going with the i7 920. Consider getting a good HSF and OCing it for even better performance.

No point getting 2 GTX 295s. A waste of cash. One of those would be way more than enough to handle any game. However, the Radeon HD 5870 is probably a better choice (at least until the HD 5870 X2 is released.)
 
This is the best-priced 2560x1600 screen IMO. I would recommend going for two HD 5870 cards (or waiting for the 5870X2, whichever you prefer) if you are gunning for this screen.

Also, I would recommend the Corsair 850HX as a great choice for a PSU; it will be able to provide plenty of power and is modular to boot.

And yes, that RAM will work nicely.
