What type of change in price can I expect?

Hey all,
I want to build a new system sometime this year and I can't decide if I should buy parts during the christmas sales or wait for potentially lower prices in 6 or 7 months.

I'm looking at something roughly like this: http://i90.photobucket.com/albums/k248/bobisadinosaur/cart.jpg


Thanks!

I understand this. I guess I didn't phrase the question specific enough.

What I was trying to say was, considering that
a) there are christmas sales going on right now and
b) the parts I am looking at (with 2 or 3 exceptions) are a few generations behind so would one expect their prices to dramatically drop within 6 months?

I am definitely building this thing either around christmas or around june. But I won't have a whole lot of use for it in between those months.

It's always a matter of buying what's the best value now. The things that drop the most are going to be video cards and cpu's. I would never buy a video card that's over $300, and heck considering the performance/prices, I wouldn't spend more than $250 on a video card. Buy the best quality power supply, case, motherboard you can afford... those components will have the most longevity. A good case will last you 3-5 years, a PSU 2-3 years, and a motherboard 1-2 years...without being too antiquated.

It really doesn't matter if it's Christmas or not... doing your homework pays bigger dividends. I try to be as informed as possible, so when it's time to pull the trigger, I don't hesitate and miss out on a good deal.... and to me a good deal is getting something I know I wanted, for a price that's just right. You get what you pay for, so I'm always skeptical if a price is too low. I'll always pay more if I know the model/brand uses better components.... it's the stuff that's been out for a few months that is usually the best value, the more mature the product, the more information you have to go on.
