Hello, I'm building a Core i7 computer.

I did an average amount of research, and I'd like an opinion on this build.

*For the rest of option 2, there is no CD drive, case, or hard drive because Option 2 is obviously more expensive. I already have those parts, and would be willing to deal with them. And for power...I have two 500 watts, I can use them together in my case, and get adapters.

My only real concern is:

-Am I missing anything really important?
-Is the Core i7 950 really THAT much better than the 920 to be twice as much money?
-And if I get the 950, do I have to get more expensive parts to really see a difference?

Also, I know the motherboard and Video is the same for both options.

If the 950 isn't all that great, I'll just get a whole new computer. That way I can sell the old one, or something. Besides, my hard drive and other components don't have a lot of life left..


Thanks guys

Thank you for this, the prices seem right. We're on a tight budget, but at the same time we're going to do this the right way. And thanks for pointing out the faster memory!

Anyone else?

Thank you for your suggestion. But why? I have a good experience with them, my current board is MSI. Would you recommend ASUS? EVGA?

All of this is going to be put into consideration.

Preferably two PCI-E X16 2.0, three I will never use. and I will only use two if both slots run at X16. Possibly hard to find. =/
